Got any numbers here?

They’re cheap enough for EV’s, but the big number here is you can get 10,000+ charge/discharge cycles. Predictions are near term ~2c/kWh grid storage looks realistic which completely changes the economics of the electricity grid. (As in whatever you pay for the electricity to charge the batteries you need to charge 2 more cents/kWh at discharge to break even.)

Pair with renewables and not only is nuclear and coal looking obsolete but even natural gas is uneconomical at current prices. Of course the economy reacts as you start to bring this stuff online which means wholesale natural gas prices could fall quite a bit etc. You also need enough wind/solar/hydro to actually charge the batteries, but that doesn’t seem to be an issue either.

For LFPs at the moment we are looking at 100->150/kwh of storage. [1]

Cycle life is around 3000->10000 cycles depending on how deep the cycles are (more shallow cycles, longer battery life). [2]

Note: Cycle life is about how long it takes for a battery to lose 20% of it’s capacity. That doesn’t mean you can’t still use it.
