94-year-old Lithium-Ion Battery Inventor Introduces Solid State Battery
- andruby 10y agoThe researchers published the paper, titled "Alternative strategy for a safe rechargeable battery" in the Energy & Environmental Science journal [0] [0] http://pubs.rsc.org/en/Content/ArticleLanding/2017/EE/C6EE02888H http://pubs.rsc.org/en/Content/ArticleLanding/2017/EE/C6EE02...
- chmaynard 10y agoThanks. I wish more science writers would provide a link to the relevant journal article.
- nyolfen 10y agonot trying to be smarmy, i genuinely know next to nothing about batteries -- are li-ion batteries not considered solid state?
- paws 10y agoI'm not an expert, but the article mentions current LiIon using "liquid electrolytes" a few times.
- patch_collector 10y agoBased on a reading of the article, apparently li-ion batteries do use liquid electrolytes to move the lithium ions around.
- piinbinary 10y agoI found this [0] when trying to answer the same question myself [0] https://en.wikipedia.org/wiki/Solid-state_battery https://en.wikipedia.org/wiki/Solid-state_battery
- nickff 10y agoNo, solid-state usually refers to a component that undergoes no mechanical or chemical change while in normal operation; conventional batteries undergo redox reactions while charging and discharging.
- deleted 10y ago[deleted]
- fuzzfactor 10y agoYou only have 3 choices, solid, liquid, or gas. If a liquid electrolyte is used, it would be a liquid-state device, not unlike a lead-acid cell or aluminum electrolytic capacitor.
- paws 10y agoTL, DR: This tech utilizes solid-glass electrolytes vs today's liquid electrolytes. This apparently brings us: "at least three times as much energy density as today’s lithium-ion batteries" "greater number of charging and discharging cycles, which equates to longer-lasting batteries, as well as a faster rate of recharge (minutes rather than hours)." The team lead is Dr. Goodenough, making things better! (sorry, couldn't resist. that's really his name) If true, that first point especially sounds awesome!
- agumonkey 10y agoI just heard about polymer electrolytes last week. Quite happy about the moves in energy storage.
- deleted 10y ago[deleted]
- mod 10y agoI used to always be excited about new battery tech, but let's be honest: we see nearly these exact claims ALL THE TIME, and they never come to market. I don't know what's to blame, but I'm to the point of "believe it when I see it."
- maxerickson 10y agoThe batteries shipping today are considerably better than the ones shipping 10 years ago.
- mark-r 10y agoYes, but not to the extent that the hyped tech over the years would have you believe. It's hard to tell how much improvement is due to new tech vs. simple incremental improvements.
- mod 10y agoWhich feels like normal, incremental improvement. The news is always game-changing. Instant charging. 3x capacity. Biggest breakthrough in years. Huge capacities for pennies on the dollar. Blah blah.
- hourislate 10y agoWouldn't it be great if this could get to market. Almost sounds to good to be true. Maybe I missed it but are there any working prototypes out there in a vehicle or some kind of device or is this just in a lab? You would think there would be folks all over this if it were the case. I wonder what is holding it up?
- gizmonty 10y agoIt's taken 25 years for Li-ion batteries to get from the lab to the current level of industrial production. If this technology pans out it will probably take a similar time to do the same - maybe a bit faster given the greater interest in batteries now.
- kbenson 10y agoI imagine (hope!) that the much larger industry and greater need for large scale commodity batteries (electric cars) can speed this up considerably, and not just a bit.
- elastic_church 10y agoand cheap credit in Europe! Make it happen!
- jaimex2 10y agoAlso keep in mind Tesla exists now and they do push the envelope. If this tech has any merit I would expect them to jump on it.
- mahyarm 10y agoSo this guy was 67 when Li-ion batteries started from the lab. And invented the li-ion battery at 57! Pretty impressive!
- callesgg 10y agoSeams like his age is irrelevant, this is a battery with 3 times the density of Lithium-Ion batteries. To me it sounds like the biggest breakthrough in battery technology that we have seen in years. That should be the story.
- matz1 10y agono, The age in the title make the story more interesting to me.
- nul_byte 10y agoI agree the battery density is the main story here, but you also cannot help but be inspired by the mans age. Just today ironically enough, I was questioning if my age might have meant I was not as sharp as I was, and then this story pops up with a man over double my age, still very active and at the top of his field. Cannot help, but be inspired.
- maxerickson 10y agoSo sodium-ion battery grid storage?
- logfromblammo 10y agoBasically, the battery has a lithium (Li), sodium (Na), or potassium (K) metallic anode, a solid glass electrolyte, and an "ink" cathode of sulfur (S8), ferrocene (Fe(C5H5)), or manganese oxide (MnO2) on a copper (Cu) current collector. So it's not entirely solid. The cathode may have a tiny bit of liquid electrolyte between the glass and the copper.

- gravypod 10y agoI'm not a materials guy but can this "shatter"? What does this mean for applications that need IP67, battery compartment stabilization?
- logfromblammo 10y agoI would guess that microfractures in the glass would impede the movement of charge carriers, even if it didn't shatter outright. It wouldn't be good for the battery to hit it with a hammer, I think, but that really applies to any high-energy-density battery. Not all glasses are created equal, either. It all depends on the composition and the cooling regime. Some glasses can shrug off small-caliber bullets, and others will crumble under your fingertips.
- vvanders 10y agoSounds awesome. Now the real question, what's the path to mass-production? If they can pull it off, it'll be a huge game-changer.
- deleted 10y ago[deleted]
- danm07 10y agoIs it just me or is Goodenough an amusingly paradoxical last name for an inventor?
- Maultasche 10y agoYeah, I noticed that too. On the other hand, an engineer needs to know when to say "it's good enough" and release it. An invention in the hands of a perfectionist may never be released.
- CodeWriter23 10y agoI don't know about paradoxical. But we know he shipped tech that was good enough.
- tomrod 10y agoAs a name for an inventor, it's good enough ;-). In all seriousness, it's a wonderful step forward. Certainly for stationary situations it's a great leap forward.

- radioactivist 10y agoHe's also well known in solid-state physics for the "Goodenough rules" [1] (more commonly called the Goodenough-Kanamori rules, but that has less of a ring to it). [1] http://www.scholarpedia.org/article/Goodenough-Kanamori_rule http://www.scholarpedia.org/article/Goodenough-Kanamori_rule
- Arizhel 10y agoWhat's really astounding is reading that, and looking at the dates. He first formulated this rule in 1955. And he's still working and making real contributions! We really need to work on greatly extending human lifespans, if for no other reason than to keep people like this alive.
- hwillis 10y agoI'm scanning the paper really quickly. I'm not a chemist but I do know a thing or two about batteries and the standard caveats apply here: When they say 3x volumetric energy density, that is the actual energy density, which is energy per liter (normal density is mass per liter). Normally people use energy density to refer to energy per kg. Because this is a solid state battery, it is much denser than normal batteries (which are roughly as dense as water). Solid state batteries are smaller but much heavier and this is no exception. It is 33% the size of a lithium battery, but for the same energy it's about 2.5x heavier. Weight is still a much bigger problem for batteries than size- batteries are much smaller than the exhaust, engine and transmission of a car, but also much heavier. The main limit on specific energy(kwh/kg) for this battery and for solid state batteries in general is voltage. Li-ion is 3.7v nominal, this battery is 2.5v nominal. 1,200 cycles may seem low, but it is actually very good; around 3x the life of current batteries. This cycle life is the time to degrade to 80% maximum storage, at a certain discharge depth and speed. Current batteries only last 300-400 cycles at their specs, but last tens of thousands at 30% depth of discharge. Problem with the above: in this particular battery, the chemistry breaks down very strongly after it reaches the end of life. Normal lithium does this too, but not as strongly. This stuff may potentially last longer, but it fails much less gracefully. Not in a dangerous way, but in the same way as a normal car often does; once its broken it'll just work worse and worse until it is barely limping. The temperature capabilities may seem irrelevant, but they are actually a decent problem for li-ion and are the reason lead acid is still used in cars. Another interesting possibility for glass solid state lithium batteries is that recycling would be very easy. In organic batteries the electrolyte burns or reacts pretty much no matter what you do, but with glass you can plate and unplate cells. Unfortunately due to specific energy, polymer solid state electrolytes are much more likely than glass (also much cheaper). Edit: IMPORTANT NOTE: this is NOT a fundamentally new type of li-ion battery! Solid state batteries have been around a while (glass, ceramic and polymer), and have specific advantages but low specific energy and power. This particular implementation is a bit higher power and possibly lower cost, but it's just a little blip of progress. Solid state batteries are a good candidate for the future, but they aren't there yet.
- darkerside 10y agoWeight is certainly a major factor in moving vehicles. Could this have more applications in something like home energy storage?
- dvt 10y agoA fantastic article for those thinking they might be "over the hill" :)
- Infernal 10y agoAnd he's still got Windows XP running in his lab, based on the photo. An interesting juxtaposition.
- budgi4 10y agoGood enough
- tedsanders 10y agoEven today, my physics lab has multiple computers running Windows XP or 2000. It's the easiest way to keep running old and sometimes proprietary software. We keep them off the network, of course. (Coincidentally, our work overlaps with John Goodenough's. He's a legend, and impressively prolific even in old age.)
- fuzzfactor 10y agoIt's not just the software, it's also the instruments themselves. The most worthwhile function of Windows turns out to be its backward compatibility. This became most apparent after Microsoft leveraged their software engineering leadership by pivoting into an anti-recycling company to make most of their money. There are incredible numbers of irreplaceable laboratory instruments made years ago which depend completely on the version of Windows that was "supported" when the instrument was issued. Since Microsoft has failed at their truly most worthwhile function, it is now necessary to put incredible effort into preserving older versions of Windows and even more difficult to preserve the older PC's. These cheap office machines, which were built to spend as little useful time as possible before progressing into their primary target duty as landfill, as electronics go were built especially crummy, just for you. Anyway, I'll be restoring a mass spectrometer shortly to operate as designed on Windows 3.1. Yes, it will cost a few thousand for the PC effort alone, but we're not going to spend 100x that amount to get a new(er) spectrometer just so it will operate using a more modern Windows version like XP or W7. There is also a great possibility that a brand new instrument compatible with Windows 10 will be completely useless in less than 20 years due to this Windows deficiency alone.
- oneplane 10y ago
- huula 10y agoHmm, the article mentioned nothing about the weight. For a medium sized quadcopter, 3 times more energy (given the same weight) means as long as 3 hours of flight time which would make all these drone delivery dream come true.
- cb18 10y agoWhat medium-sized quadcopter has an hour long flight time? Is this something you follow very closely? Do you know of any write-ups on the economics and other feasibilities of drone delivery? Seems like for a cargo of any much heft and a delivery distance beyond a handful of km a battery improvement of 3x is a good start but still wanting. I may be off base here and drone delivery may in fact currently be more feasible than I suspect. I'm mainly basing this thinking on the 20-30min flight times of current prosumer camera drones. I know there're other kinds.
- eridius 10y agoUnfortunately, as hwillis explains in another comment (https://news.ycombinator.com/item?id=13779143 https://news.ycombinator.com/item?id=13779143), it's not 3x energy for the same weight, it's 3x energy for the same size. It seems to actually be about 2.5x heavier for the same energy.
- rebootthesystem 10y agoA comment that I think is relevant in a community of startups that often, explicitly or de-facto practice age discrimination: This engineer is 94 years old. Few, if any, SCV startups would have hired him. Yet, here we are, he might have just developed the key technology to push electric transportation through the hockey stick curve past the inflection point. Three times the energy density, many times more cycles, no shorting, high charge and discharge rates. Yeah, this is more than just about laptops and cars, this is about planes, boats, trucks and ships. Think about that before you reject a 50+ year old. Experience has real value.
- slantedview 10y agoThis 10000 times.
- mikekchar 10y agoI don't want to take anything away from Dr. Goodenough, but there is a slight caveat with respect to academia. Older, established, and respected researchers are able to attract large teams of of highly talented people. They are also able to secure funding. It is usual that this leader is given top billing on all papers and press interactions, even if they are mostly coordinating the work. This is good for everybody because the lab can continue to attract good talent and especially it can attract funding. Brilliant young researchers working by themselves in obscurity can't really make much headway because they have neither the man power, nor the money to tackle big problems. So, while I agree with you in principle, older researchers offer more in academia than just their experience.
- sndean 10y ago> This engineer is 94 years old. Few, if any, SCV startups would have hired him. Possibly more relevant than what he's doing now, at 94: As far as I can tell, his main breakthrough that led to the Li-Ion battery was in 1979, when he was 57 (?).
- ChuckMcM 10y agoI have put a note in my calendar a year from now, and a year after that to read the story about how these laboratory curiosities could not be made in production quantities. Something I would really love to see would be a solid state battery that exploited the fact that we can draw silicon features at 7nm. How about a couple trillion equivalents of a FLASH cell which we can drain in rows or fill in rows. Sort of a bucket brigade of capacitors at that point but it would not have any recharge issues and since its just charge flying about no dendrites to speak of. At some point I predict that will become a useful way to build energy storage devices.
- hwillis 10y agoYou are actually absolutely correct, silicon and all! https://en.wikipedia.org/wiki/Nanowire_battery https://en.wikipedia.org/wiki/Nanowire_battery The reason why is different and it doesn't solve dendrites, but your conclusions are spot on.
- beambot 10y ago> story about how these laboratory curiosities could not be made in production quantities Why would you just want to be cynical about fundamental battery research? This is how all big breakthroughs happen: in fits and starts.
- ChuckMcM 10y agoIt is more battery breakthrough fatigue. Last time I looked there was something like 17 - 18 battery "breakthroughs" over the last 8 years of which exactly one made it into production for a relatively small (10%) improvement in charging performance. These laboratory curiosities usually fail because either you can't reliably manufacture the precursor material or reliably make the structures needed at production rates (which translates into the cost of the resulting battery) It came up in a discussion with some Tesla enthusiasts on the ground breaking of the Gigafactory where I wondered if there would be a break through that would make the batteries the Gigafactory would produce obsolete before they finished building the factory. That didn't happen :-). As a result I recognize its a really hard slow slog through chemistry which is well understood to change batteries. And you're correct there have been a number of improvements in manufacturing which have resulted in incrementally better batteries and that is all good, but so far, starting with a basic battery and making a new battery that is significantly better, has been disappointing.
- rhodin 10y agoInteresting footnote: "The UT Austin Office of Technology Commercialization is actively negotiating license agreements with multiple companies engaged in a variety of battery-related industry segments." I recommend the book "The Powerhouse: America, China, and the Great Battery War"[1], it goes into some detail about the legal issues around (one) li-ion design and Thackary's work with/without Goodenough and attribution.

- bitmapbrother 10y agoI was watching a Nova episode on batteries and they showed a new type of Lithium Metal battery that used a plastic material that separated the positive and negative halves. The unique thing about this new Lithium Metal battery was that it was not prone to the existing problems of Lithium Metal batteries and did not catch fire when punctured. They even started cutting portions of the battery off with a scissor and it continued powering an iPad.
- hwillis 10y agoYup, same principle. The problem all solid state batteries share is that the solid electrolyte isn't a good conductor- plastic isn't great for that. Despite that it's the current favorite for reasons of cost. NB that the plastic is very very special.

- agentgt 10y agoI have not examined the article yet but I was somewhat impressed with Mike Zimmermans work: http://www.pbs.org/wgbh/nova/next/tech/new-damage-proof-battery-has-higher-energy-density-wont-explode/ http://www.pbs.org/wgbh/nova/next/tech/new-damage-proof-batt... Yes the linked Nova show has that goofy host but it still pretty interesting and is young adult / kid accessible. I highly recommend seeing the whole Nova show if you can.
- philipkglass 10y agoThe press release says "the researchers’ cells have demonstrated more than 1,200 cycles with low cell resistance." That's nice, but rising cell resistance is just one way the battery might cycle poorly over time. Skimming the actual paper, I don't think they demonstrate 1200 cycles for any parameter. Eyeballing the graphs, it looks like they did charge/discharge testing for maybe 1200 hours (Figure 3a), but with really slow charge/discharge cycles of 10 hours each. Anyone publishing in this space would highlight 1200 cycles of stable cycling in the actual paper, if they had data to demonstrate it. They'd also show off faster cycles if high-rate performance looked good. Looking at the data the authors did not present in the actual paper, I'm guessing that this battery doesn't handle rapid charge/discharge cycles well. (Their cycling test is at only 0.1C, paper claims "acceptable charge/discharge rates" but does not further quantify it... implication is "not a strength of this design.") It may not have great capacity retention either. I don't see any graphics specifically highlighting capacity retention vs. cycles. So at present I'd call this a solid research effort, but even if it could be commercialized immediately it's not clear that it would be a winner. The demonstrated charge/discharge rate is too slow to be practical for EVs or portable electronics. The demonstrated cycling stability is too low to be attractive for grid tied storage. People who found this paper interesting may also be interested in this related publication about solid state sodium ion batteries that Goodenough was also involved with: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5269650/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5269650/
- djsumdog 10y agoI really wish they'd publish more of the limitations as well in the paper. I wonder how much of it got cut out in editing. Publishing limitations and negative results that lead to dead ends can help other scientists when they attempt to replicate and improve on tech like this.
- philipkglass 10y agoI agree that publishing negative results would help the whole enterprise of science, but the prisoner's dilemma is pretty clear. I would guess that the authors have been "trained" well enough by publication incentives that they didn't bother to highlight limitations even in their original manuscript. That kind of information shows up in the paper only by absences and implication; it's only informal chats with peers where people talk honestly and thoroughly about the negative results and limitations of their approaches. It's a shame that scientific publication ended up this way. It's one of the reasons I left research to write software.

- angryasian 10y agoI hope when I'm 94 I'm still as productive as this man is
- fndrplayer13 10y agoThis may be a silly question to ask, but forgive me, I dont know much about EE or battery technology: Its my understanding that current batteries found in mobile phones, laptops, etc make use of rare earth minerals which are limited and expensive and only available from big players like China. Does anybody know if this technology also makes use of rare earth minerals?
- hwillis 10y agoNiMH batteries used lanthanum, but we don't use NiMH any more. Li-ion batteries use heavy metals, specifically cobalt, of which China is the largest buyer. Almost all cobalt comes from Congo though. Cobalt is widely available everywhere, as are rare earths. Congo just happens to have a freakishly high amount of it plus cheap everything, so it is widely mined there. Unlike other technology mining easily transfers and it doesn't take much time (a few years) or money to open new mines. This battery doesn't use cobalt at all, and most newer batteries use significantly less cobalt or none at all (LiFePO4). Phones and batteries still use a lot of cobalt, and are major consumers, but the biggest consumer is machine tools.
- ASpring 10y ago> Another advantage is that the battery cells can be made from earth-friendly materials.
- fndrplayer13 10y agothank you, I totally missed that. That's awesome!
- dsparkman 10y agoNo rare earth minerals.
- grhmc 10y agoSounds like John Goodenough wouldn't leave goodenough alone.
- 33a 10y agoThis sounds like it could be really nice for off grid solar set ups if it was cheap enough.
- djsumdog 10y ago> Maria Helena Braga I don't want to diminish what this guy has done, but I hope all the other people involved get the credit they deserve. The sole inventor is for super hero movies. In reality, there are teams, sometimes just 6 ~ 12, but sometimes dozens of engineers and scientists, grad and undergrad students, that work together to figure out all the little parts to make technology like this work and make it viable. It's never just the first author, but the next six or so authors on a paper that helped make a project what it is. All that being said, it's still cool to see research institutions working to make stuff like this.
- temp246810 10y agoI don't understand, the first 2 lines of the first two paragraphs: >>>A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering >>>Goodenough’s latest breakthrough, completed with Cockrell School senior research fellow Maria Helena Braga Further down: >>>Braga began developing solid-glass electrolytes with colleagues while she was at the University of Porto in Portugal. About two years ago, she began collaborating with Goodenough and researcher Andrew J. Murchison at UT Austin. Braga said that Goodenough brought an understanding of the composition and properties of the solid-glass electrolytes that resulted in a new version of the electrolytes that is now patented through the UT Austin Office of Technology Commercialization. I understand the sentiment, but I don't think it was needed in the context of the article. And while you don't want to dimish from what that guy has done, in a way you diminish the message of the article by singling out a name that the article did not. Hope this doesn't come across as overly antagonistic, just thought it was odd considering the article seemed pretty good.

- nimos 10y agoThe greatest travesty in the world right now is there doesn't exist a multi-government 10xManhattan sized project to develop a really really good battery. It would enable a huge reduction in CO2 emissions(bye gasoline), allow developing countries have stable electrical sources and low cost renewable distributed generation, cut costs(good includes cheap), and enable renewable energy sources to make up a larger mix of our energy production. Always exciting read about new developments, wish I knew more about chemistry/physics, hopefully we get there sometime soon!
- dkural 10y agoPeople don't have great ideas on what they'd do with new monies that would come a 10xManhattan size project. Tesla, VW, Toyota, Dept of Energy, DARPA, NSF, Energy Companies, Industrial Conglomerates like GE, Panasonic, etc. all work on battery research. (& many more) The actual Manhattan project could spend the funds by building reactors with desirable end-products (uranium etc.) and building a lot of centrifuges to refine it further - along with engineering teams to design, build, and operate these things, various bomb and delivery mechanisms etc. It was the very beginnings of nuclear science, so there were many fundamental ideas to be discovered and tested out - it meant sense to spend a lot of money to travel and explore this newly discovered branch of the tree of knowledge.
- afsina 10y agoGovernments cannot invent or develop technology, they only hinder it.
- bluejekyll 10y ago> Braga began developing solid-glass electrolytes with colleagues while she was at the University of Porto in Portugal. Slightly orthogonal to the content: this is why it's important for the US to allow people to come to this country. Continuing research and development with the worlds best gives the US a leg up. Past ease of immigration is the reason the US has led in so many areas, constant flow of new and innovative ideas.
- Oxitendwe 10y agoLiterally no one is arguing to the contrary. The problems people have with immigration into the US typically involve the sheer scale of it, the fact that many people who come to the United States do so illegally, difficulty with integrating, and difference in values from native citizens. Nobody is arguing against small-scale immigration of highly skilled scientists, there aren't even enough of them to make a demographic difference.
- hoppa_liza 10y agoA few days ago some Indian engineer was shot dead because he "looked Iranian". There is a very strong political reason why people like this killer do what they do.
- deleted 10y ago[deleted]
- Oxitendwe 10y agoPerhaps I should have clarified: by "literally nobody" I meant "virtually nobody", as in "the number of people who believe that we should accept no immigrants whatsoever is very small and statistically negligible".
- bluejekyll 10y agoI'd say the current stories about people enforcing poorly written rules at the border prove you wrong. People say yes to scientists, but not if they're from certain countries. On top of that we have scientists from Europe being stopped at the border, making it unlikely that they or their compatriots may try to make the trip in the future. I know of at least one computer conference that has discussed moving the venue outside the US to try and mitigate the issues at the border. While you may be right that no one debates elite people in their respective fields from moving or coming to the US, the enforcement is causing exactly the opposite to occur. So, I respectfully disagree with you that what you suggest would be acceptable.
- cb18 10y agoI don't know why people conflate these things. Policies intended to limit exposure to backwards, barbaric culture and ideas, and to low skill individuals is not shutting the US off to new and innovative ideas, in fact just the opposite. The US has a carrying capacity of only so many people, might as well make those people the ones most likely to have new and innovative ideas. New and innovative ideas come hugely, disproportionately from Europe and people of European descent, no one is saying immigration of Europeans to the US should be restricted.
- hoppa_liza 10y agoRacism does not get any better when you use fancy words. Your exact line of thoughts went through the killer that shot that Indian engineer. The difference is that he was less eloquent.
- Oxitendwe 10y agoI don't think it's right to equate expressing unpopular opinions with murder, no matter what you believe. If he's wrong, prove it, there's no need to resort to such ad-hominem attacks.
- hoppa_liza 10y agoI did not equate actions. I equated thoughts. Two people think the same thing; one chooses to curse, the other chooses to murder. Trump has not killed anyone himself, but his supporters have. Are you telling me there is no link between their thought processes?

- fuzzfactor 10y agoTurns out that occasionally an inventor appears who gains more lifetime experience than over 99.99 percent of their "peers". This always requires more decades than most people expect. And some of these technology creators are the kind that can go from nothing to something in only a couple years, not unlike the way a software developer can sometimes go from learning basics to an incredibly effective breakthrough app in just a couple years themselves. Then you give them decades and it's amazing. With some of them it's so natural that they get better every year, until there is no way anyone else can compare in only just a single decade or two. These are the operators who if properly capitalized can create the most jobs.
