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 1 points 3 months ago (1 children)

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

[–] KillingTimeItself@lemmy.dbzer0.com 1 points 3 months ago (1 children)

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 2 points 3 months ago (1 children)

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.

yeah, you would expect it to slow down over time, given the ever encroaching theoretical limits of technology, but obviously that depends on how far that is from here. Otherwise you generally expect to see an increase likely proportional to the amount of sold product (more R&D funding) as well as a function of competition, which is pretty high right now.
