EV batteries alone could satisfy short-term grid storage demand as early as 2030

What if your car battery had a chemistry that could sustain ~10000 cycles if well handled, and aging in general was a bigger issue than cycle degradation?

We’re approaching this with the recent LFP generations.

LiFePO4 batteries I bought in 2017 were rated for 4000 cycles of 80% depth of discharge. Shallower discharge counted as partial cycles. Even at such a heavy use, that's almost 11 years of heavy use every single day -- after which the battery still continues to operate just fine, with slightly lower capacity.

People are afraid of actually using their batteries, and engaging in FUD about their aging. It's weird.

And some of the same people change cars a year later (talking about EVs, of course — because it doesn't have HW4, 4680s, etc.). Some of it is human nature, though.
