Are Graphene Micro-Supercapacitors An EV Gamechanger?
Energy density isn’t the only reason why battery-powered cars have never caught on. As was highlighted in Tesla’s somewhat less than successful media road trip, the amount of time it takes to fill batteries with electrons can be as significant a factor in the practicality of EVs as the amount of electrons those batteries can hold.
