What happened to Goodenough's improvement some years back that was supposed to triple the capacity of batteries, per unit weight?
I see them getting cheaper, but it doesn't seem like capacity of a cell has improved much.
- Tagbert 5y agoBattery tech has been improving steadily on various fronts over the last decade. The changes are incremental but happen frequently and have added up a lot over the years. https://arstechnica.com/science/2021/05/eternally-five-years-away-no-batteries-are-improving-under-your-nose/ https://arstechnica.com/science/2021/05/eternally-five-years...
- ncmncm 5y agoObvs, and capacity per unit weight is one such front. But my question was specific: he said 3x, coming to market in 3 years, or by 2020. It has been longer, and capacity is up nowhere near 3x in places I watch. Is it still to come, or did it not pan out? Judging from the link in the other reply, it is not expected until well after 2026. Shame he (probably) won't get to see it.

Hydro Quebec is developing it. https://electrek.co/2020/04/23/work-on-goodenoughs-breakthrough-solid-state-ev-battery-moves-forward/ https://electrek.co/2020/04/23/work-on-goodenoughs-breakthro... They're also commercializing something with Mercedes-Benz, but I can't tell if it's the same tech. https://news.hydroquebec.com/en/press-releases/hq/1580/hydro-quebec-partners-with-mercedes-benz-on-development-of-solid-state-battery-technologies/ https://news.hydroquebec.com/en/press-releases/hq/1580/hydro...
