1. Battery is a source of energy for a circuit, whereas capacitor is a passive element, which draws energy from the circuit, store and release it. 2. Usually battery is a DC component, whereas capacitor is mostly used for AC applications. It is used to block DC components in circuits.
Due to the fact that a supercapacitor does not suffer the same wear and tear as a chemical reaction based battery, it can survive hundreds of thousands more charge and discharge cycles. Supercapacitors boast a high energy storage capacity compared to regular capacitors, but they still lag behind batteries in that area.
