Reminds me of the "revolutionary battery checklist": https://news.ycombinator.com/item?id=28025930 https://news.ycombinator.com/item?id=28025930

- dzhiurgis 3y ago“No week goes by without a revolutionary battery technology” - Engadget, circa 2010
- gibolt 3y agoWhile this is true, a tiny start-up with big claims is different from the world's largest battery manufacturer (CATL) already spooling up production with the intent to scale.
- jackmott42 3y agoAnd that is why batteries have become so much better now than they were 20 years ago.
- magila 3y agoEh, not really. Most "battery breakthrough!" press releases are about some new exotic chemistry while most mass produced battery improvements in the last 20 years have come from incremental improvements to existing chemistries and better packaging.
- _ea1k 3y agoMeh, the devil's in the details with a lot of those announcements. A surprising number of them are things like... it will be 50% better 5-10 years from now! That's actually incremental improvement if you think about it in annual improvement terms.
- zamnos 3y agoIt is, except for the fact that the future isn't guaranteed, so there could be unforeseen problems with scaling up, and that 50% improvement never gets delivered. As mentioned upthread though, CATL has expertise in that area, and "end of this year" is so a trackable claim, unlike the claims about gallium-based batteries.
- _ea1k 3y agoI agree. Its also not uncommon that the "old" tech improves incrementally during the same timeframe, mitigating the seeming impact.
- Schroedingersat 3y agoHard carbon anodes were one of these "exotic" new elements, but are now just standard. Silicon anodes will be the same. Sodium ion still has shills screeching about how it'll never come despite being last year's news. Lithium Manganese batteries are another one of these exotic chemistries that arrived without fanfare.
- usrusr 3y agoHave they? Other than lithium based batteries getting cheaper per kilogram so that year by year, more battery use cases have switched over from inherently worse chemistries? Even just ten years ago, eneloop were still the hot thing for many applications outside of laptops, mobile phones and the odd Tesla (ten years ago was when Model S was still the fresh new successor to the converted Lotus)
- rootusrootus 3y agoIs eneloop not still very much a thing? Maybe not the brand, but the technology. The vast, vast majority of consumer devices using standardized battery sizes are AA or AAA, and that means NiMH. To go lithium means 18650, and I don't really see much of that happening outside flashlights and other niche products.
- s5300 3y agoWhy does going lithium mean 18650? 14500s have always existed. I think there’s even smaller than that but I haven’t personally checked in a bit.
- adoos 3y agoForm factor smaller than 1865 with energy dense formula is rare. Chinese made LFP but only a handful of mfgs make them anymore. So size doesn't matter, but it basically matters :D
- deleted 3y ago[deleted]
- chriscappuccio 3y agoLFP is going to be manufactured in north america soon
- eternityforest 3y agoNothing except flashlights and yard lights seem to use them either. Probably because they're not exactly safe enough for frequent swapping applications, consumers will drop them on their tin foil crack smoking rig and make a fire or something.
- notJim 3y agoCheap cynicism is fun, but Wh/kg has been steadily increasing since the '90s https://arstechnica.com/science/2021/05/eternally-five-years-away-no-batteries-are-improving-under-your-nose/3/ https://arstechnica.com/science/2021/05/eternally-five-years...
