EEF-SR0D221R4 Capacitors Working Principle

An aluminum-polymer capacitor works on the principle of electrical charge storage, through the use of two different capacitors connected in series. The first of these two capacitors is the aluminum-polymer capacitor itself. This capacitor is composed of an polypropylene or polyethylene dielectric filled with an aluminum or a zinc electrolyte. This electrolyte can also be filled with a variety of polishing additives or different salts.

The second capacitor consists of an aluminum anode and a separate aluminum-based cathode. The anode and cathode are connected in series, and the aluminum electrolyte has a higher energy state than the zinc electrolyte. This higher energy state produces the capacitor’s electrical charge. When electrical current is applied, the aluminum electrons are drawn to the surface of the anode, and the zinc electrolyte will release its electrons to the cathode. This process stores electrical energy, which acted as the capacitor’s energy source. When the current is stopped, the anode will regather its electrons, and the cathode will recieve electrons from the zinc electrolyte. This process releases the stored electrical energy and discharges the capacitor.
