Well, this topic went south really fast! I'm surprised the new Goodenough battery design hasn't come up!
Getting back to an actual discussion of lithium, it'll be very interesting to see if the Goodenough solid electrolyte batter works well enough with sodium. If so, a lot of expensive lithium mines will be worth a lot less over time!
The Goodenough battery (he invented LiON batteries for those who don't know) looks to improve on LiON in most important areas:
- higher energy density (~2x)
- not flammable
- faster charge rates
- many more charge cycles (~100x more)
- better performance in cold conditions
- either lithium or *sodium* based glass electrolyte
Apparently 89 companies are evaluating the patents for production:

- FrojoS 7y agoIt took me a while to get, that Goodenough is the name of the inventor (John Goodenough) and not a tacky brand name.
- Recurecur 7y agoHis name should already be famous, but it sure will be if this new battery works out. Phones that fully charge in five minutes, then last twice as long...and can go for many thousands of charge cycles? Count me in!

Here's another interesting battery from a company called XNRGI: https://www.digitaltrends.com/cool-tech/xnrgi-develops-ev-battery-tech-that-extends-range-to-700-miles/ https://www.digitaltrends.com/cool-tech/xnrgi-develops-ev-ba... We'll have to wait and see if it lives up to XNRGI's claims.
- hwillis 7y agoGoodenough didn't invent li-ion, he invented the cobalt oxide cathode that dominated the industry until nickel and iron cathodes came along. Goodenough is 97 years old and while he is still apparently sharp, he is not leading the lab that gets publicity under his name. From what I've seen he's more of a mentor. I, and many others[1], are extremely skeptical of the claims coming from that group. At best, they have been putting out very misleading papers that gloss over key factors or lie by omission to make their research look like they're making massive breakthroughs. At worst, many of their claims break basic rules of conservation of energy. Either way they haven't given much evidence they have a better battery. One of the ways they produce these claims is by creating several cells, each optimized for maximum performance in one area while totally sacrificing every other metric. Then they put every good metric in the abstract and conclusion, while if the battery was balanced for lifespan, power, and capacity it would perform poorly in all ways. Beyond that they also make some absurdly high ion mobility claims in mundane materials, and nonsensical energy balances. Honestly, it has a lot of signs of bunk science... but it does seem mixed in with good (but routine) work, so it's kind of perplexing.
