Estonian company specializing in ultracapacitors, which is working on a supercap/lithium hybrid "SuperBattery" for electric vehicles
We got it wrong, folks. The Superbattery from Skeleton Technologies is not a hybrid battery/ultracapacitor energy system, it's an entire new type of cell that sits somewhere in between the two. And it will make it into EVs – just not how we expected.
Estonia's Skeleton Technologies and Germany's Karlsruhe Institute of Technology have partnered up to complete development on what they're calling the SuperBattery for EVs – "a groundbreaking graphene battery with a 15-second charging time."
