Capacitor	Battery
The potential energy is stored in the electric field	The potential energy is stored in the form of chemical energy which is later converted to electric energy
It is a passive component of a circuit	It is an active component of a circuit
Lower energy density than a battery	It has a better energy density than a capacitor
Charging and discharging rates are faster than a battery because it stores energy directly on to the plates	Charging and discharging rates comparatively slower because of the conversion of chemical energy to electrical energy
Discharges instantaneously	Runs for a longer time
Voltage decreases rapidly while discharging	Provides a constant voltage
Higher cost	Comparatively cheaper than a capacitor
A capacitor is composed of thin sheet metals held close together or separated by an insulator	Composed of metals and chemicals
