Lower power density, higher cycle life, safer. Sounds good for stationary power storage.

And commuter cars probably. I'd love something I can drive to work and back, and then later upcycle into home energy storage.

CATL showed a 160 Wh/kg sodium-ion battery in 2021 and has plans to increase that density over 200 Wh/kg to better meet the needs of electric vehicles.

Hopefully that happens in a reasonable timeframe. I don't need high range, I just need cheap to repair or long life for a commuter. Maybe we'll get something similar for buses and light rail first before getting it for regular cars.

Amazing how far we're progressing in battery technology in such a short amount of time.

And all it took was $100/BBL gas to get people off their asses. A shame we weren't pioneering this kind of research 40 years ago.

I remember NiCad batteries still being used in power wheels toys as a kid. For all I know they may still be, but the battery advancements have been particularly amazing.
