100 Year 4 Million Mile Car Battery?

That seems significant to me. It’s an extrapolation of course; nevertheless
seems important,

The LFP chemistry has lower energy density than more widespread Lithium-Ion alternatives, but is cheaper, more durable, and allegedly safer, too. LFP can last up to 12,000 charge-discharge cycles, so beating it in this regard is no mean feat. Dahn’s NMC 532 cells showed no capacity loss after nearly 2,000 cycles. The paper extrapolates this out to imply a 100-year lifespan (they obviously haven’t been testing the battery that long).

I wonder if it has same recharge rate( faster,slower, same) as Li ion ?

But they are more likely to be most useful for static energy storage in houses and for grid buffering capacity from an intermittent renewable supply.

Thanks for posting this.
