Skeleton Technologies announces graphene superbatteries charged in 15 seconds
What exactly are we talking about? Most likely, a hybrid solution that combines traditional lithium-ion cells and ultracapacitor cells, in which we find a proprietary curved graphene structure, using the strengths of both technologies. Simply put, lithium batteries offer a high energy density, which means they can store a lot of energy, but unfortunately they take a long time to charge and discharge - this is why electric cars take so long to charge, which is a bottleneck in the development of this industry. Supercapacitors, on the other hand, charge and discharge quickly, but are not able to store too much energy, so they are not yet used in electric cars, for which they are even made, because the batteries based on them would be huge.
