and lithium tech has only gained a few percent a year

isn't it about an 8% improvement year on year historically?

[–] ColeSloth@discuss.tchncs.de 0 points 3 months ago (1 children)

I double checked. It looks like about 5% per year.

yeah that seems about right, it's still pretty good though.

Over 10 years that's 50% more capacity compared to older cells.

[–] frezik@midwest.social 0 points 3 months ago

It's actually been about 8% in recent years, but historically 5%. We'll see which one holds, but either compounds to doubling capacity in shorter time than you might think.
