- chopin 2y agoA 10% increase per year is exponential.
- illiac786 2y agoyes, ok, but it’s far from e. Let’s say “exponential” is a shitty term, it can mean very different things. But 10%/y is still a doubling within 8 years, so maybe not so bad – if my memory is correct. [edit] see other comment, it is indeed very much linear, not exponential at all.
- _visgean 2y agoThere is a chart here: https://www.researchgate.net/figure/Advances-in-energy-density-of-selected-battery-types-by-year_fig2_294580055 https://www.researchgate.net/figure/Advances-in-energy-densi... I am a bit confused by the units but it seems to be growing, tho the data cuts off at 2005. Another chart is here: https://physicsworld.com/a/lithium-ion-batteries-break-energy-density-record/ https://physicsworld.com/a/lithium-ion-batteries-break-energ..., still does not seem exponential, looks kind of of linear to me.
- illiac786 2y agothe first one shows linear progression, not even 10%, except the prototypes at the end. Second one shows a linear progression too it seems, I agree.
