While batteries and capacitors are both energy storage devices, they differ in some key aspects. A capacitor utilizes an electric field to store its potential energy, while a battery stores its energy in chemical form. Battery technology offers higher energy densities, allowing them to store more energy per unit weight than capacitors.
