In the industrial market, it is used in hydraulic, electric, and hybrid power transmission systems, and it is commonly used in solar energy storage and distributed energy storage systems in the energy market.

Working Principle

Aluminum-polymer capacitors take advantage of the high power properties of aluminum and the electrolyte properties of polymers to provide superior performance and stability. The core of the capacitor consists of two aluminum electrodes that are separated by a separator. The separator is a polymer gel-like material that is saturated with an electrolyte. This structure gives the capacitor polarized, non-polar, and wet electrolyte capacitance, which are all important performance characteristics. These characteristics are what give aluminum-polymer capacitors their superior performance and reliability.

When a current is applied to the capacitor, the aluminum electrodes react with the electrolyte in the separator, creating an electric double layer. This double layer forms the electric field that stores energy in the capacitor. As more current is applied, the electric field becomes stronger, resulting in higher capacitance, but also in a larger voltage drop across the two terminals. As a result, aluminum-polymer capacitors can handle high power demands while still providing good stability.
