The device is also suitable for various energy-storage applications, such as high-speed rectifier circuits, mobile phones, digital still cameras, and electric toys.

Working Principle

Each aluminum electrolytic capacitor consists of a cylindrical capacitor element which consists of two or more conductive plates that are separated by a dielectric material. The two plates are an anode and a cathode. The two plates are dipped into a liquid electrolyte solution, which provides mobile ions to the system. This creates a charged differential across the plates and produces a capacitance.

When a voltage differential is applied across the two plates, electrons are drawn from the anode to the cathode. This creates a current flow between the two plates, which results in a charge differential and the development of a capacitance. This is a reversible process, meaning that when voltage is removed, the charge is released from the plates and stored energy is dissipated as heat.
