Ultracapacitor VS Battery
The supercapacitor is a kind of electrode material made of carbon-based active material, conductive carbon black, and binder. The polarized electrolyte is used to adsorb the positive and negative ions in the electrolyte to form an electric double layer structure for energy storage. The energy storage process basically does not occur chemical reactions, so the cycle life is very long.
