This post will give details on the NMC 622 cells currently being used in the Chevy B olt and 40kWh Nissan L eaf. NMC 622 has a higher energy density than previous chemistries. One problem though seems to be the higher energy density of the cathode, does not allow for a similar increase in charging power because of limitations in the anode.
Update: this also seems to be the cell used in the new K ona EV.
----------------------------------------------------
Using info from this article - Jaguar and Chevy have LG in common we can find the stats for the B olt EV cells.
Found this battery cell on sale at Alibaba - 3.7V 60Ah lithium polymer rechargeable battery for EV power tools


Having the exact size, weight and capacity of this cell will allow us to compare this current generation cell with the soon to be released NCM811 cell.
This cell appears to be the same one used in the Chevy B olt EV. - see Inside the factory building GM's game-changing Bolt EV

increase in range capacity comes with a decrease in max charge rate.

the core reason is that the anode powder (carbon) has a strong inverse relationship between charge rate and safety (plating)
