EV energy boost: Breakthrough plasma treatment could double supercapacitor capacity

Scientists at Skoltech have discovered a way to double the energy storage capacity of supercapacitors using plasma treatment. By applying a mixture of nitrogen and argon plasma to carbon nanowall electrodes, they increased areal capacitance by 100%. This breakthrough could lead to more powerful supercapacitors for use in electric vehicles, trains, and other applications requiring quick bursts of energy. The improved supercapacitors could complement batteries, offering faster charging, wider temperature ranges, and longer lifespans.
