That shows to me that there is a fundamental theoretical limit being
approached here. The chemistry we are using can't do any better.

Are there any other chemistries that have potential? If not, we are ****ed.

Its not all about the chemistry, the designs are being improve to increase
energy density and reduce charging time.

Energy density is ABSOLUTELY a function of the chemistry.

Chemistry AND cell design.

Do you think the surface area of the electrodes is irrelevant to energy
density of a battery?

That would be a bit second order - unless the first cells were designed really
stupidly.


So you would say that there been no progress in lithium cell capacity in
the last 5 years? That EV range hasnt improved dramatically over this
time?
