The Difference between Supercapacitor and Battery
Difference between battery and supercapacitor 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. The difference between supercapacitor and battery are as follows: For batteries, for example, lead-acid batteries use lead plates filled with spongy lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 1.28% dilute sulfuric acid as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy. When the battery is discharged, the metallic lead is the negative electrode and undergoes an oxidation reaction and...
