In terms of energy storage capability, the commercially accessible supercapacitors can offer higher energy density (e.g., 5 Wh kg −1) than conventional electrolytic capacitors, though still lower than the batteries (up to ≈1000 Wh kg −1).
In comparison, a supercapacitor stores energy electrostatically. The unique design of supercapacitors allows for rapid charge and discharge cycles. While batteries typically offer higher energy density and longer-term storage, supercapacitors excel in delivering quick bursts of energy.
