Weird, I didn't know Lithium-Ion batteries were still in the lab. I thought for sure we were using those already. I thought the batteries in the labs were various solid-state batteries like graphene or like this sodium-ion battery, where there's been a rise in patents around it but not a lot delivered

There are a bunch of lithium ion chemistries that have come to market more recently.

LFP sits in the low cost marker while NCA is the highest performing of the mass market batteries, and NMC is somewhere in between.

Sodium might be coming for LFP's low cost position, and is already beginning mass production (some Chinese manufacturers expect those models to hit the road in a few months).

If you think rechargeable battery R&D from 10 years ago isn't making it into mass produced products today, you're just not paying attention.

If you think rechargeable battery R&D from 10 years ago isn’t making it into mass produced products today, you’re just not paying attention.

Please provide examples.

I mean, as much as a person who doesn't work in research and development of energy storage, or work in industries directly related to it, I personally feel I've kept up. The day Donut Labs announced their battery I was watching review videos about it, and I want to believe, but until I see it for purchase, I'm not going to call it a win.

Wasn't LFP commercialized at EV scale like a decade ago? It went from like 0% market share to majority market share in about a decade.
