There still hope for electric vehicles

Ciorrect me if I 'm wrong, but that 20 kw/kg can only be delivered at 80,000 volts ? You'd need some heavy industrial grade insulation on the wiiring loom and some extensive step down transformers on board to get a usuable output. The home charger would be impressive too. And a quarter if amp oer kilogram is less than lead acid @ 60-80 amps per kilo.

How long would a battery charged to that voltage be able to hold a full charge and what iact would cold have on the delivery of that high voltage ?

Although oublished in Nature (Is tbis the actual Nature or a Chinese version ?) I wondering if there us a silly season for publishing scientific papers ?

It is just prime materials science research. It is based on masssively increase energy density via increase in electrolyte contact surface using a solvent as catalyst for carbon substrate. At the end they describe the testing methodology and it writes it was tested between 1.5V-4.5V and not 80,000V.

Where did you get the 80kVfigure from ?

As far as I know this is the real Nature
