So it took us 25 years to get a 2x density improvement in li-ion cells.
We desperately need higher density but it is very slow going. The density necessary to "save" EVs for the layman is unfortunately not coming soon.

And then the BMS, thermal management and charging improvements and greater provision all allow for smaller batteries (which reduces weight and allows for smaller batteries recursively). Not to mention cost reductions in batteries and electrcity. Overall a 2023 EV is more than 2x a 1997 EV.
