Supercapacitors are storage devices capable of charging and discharging with high speed. Unlike conventional batteries, which use chemical reactions to store energy, supercapacitors use electrostatics. This means that they can be charged and discharged much faster with a much longer lifetime than batteries, being able to cycle hundreds of thousands of times. However, most supercapacitors currently used can only store small amounts of energy compared to batteries. This depends on their porous lay...
