first thought
increase for lowest density is from 60 to 105 over 5 years (75%), so 9 (Whr/kg) pa
average is from 85 to 125 over 5 years (32%), also 9 (Whr/kg) pa
higherst density increase is from 137 to 153 over 5 years (11%) , 3 (Whr/kg) pa
 
2nd thought
Renault Zoe / Hyundai ioniq
similar year & tech pool
Renault gets about 50% more capacity but with about 1/3 of the charge rate acceptance.
thats the trade-off between density vs quick charge ability
