I've been hearing about these for a few years now. Huge if they work out at a large scale.

If it's cheap and abundant enough you can have overcapacity and it easily lasts 30 years - which apparently is an important breakpoint for infrastructure project funding.

    It's the maintenance period on lots of infrastructure.

    What it means isnthe private investors are more likely to bid to build power storage infrastructure for governments because it's less likely they'll ever have to change out the cells during the contract.

    On the flip side, governments would kinda like them to work for 25 years so they'll go 50 years without having to buy new cells.
