Double layer capacitor, also known as electrochemical capacitor, gold capacitor, Farrah capacitor and super capacitor, is an electrochemical element that can realize energy storage through polarized electrolyte.
electronic components distributor says that unlike traditional chemical power supplies, it is a power supply with special properties, between traditional capacitors and batteries. It mainly relies on double layers and oxidation to reduce false capacitive charges to store electrical energy. However, there are no chemical reactions in the energy storage process. This energy storage process is reversible because the dual-layer capacitor can be recharged and discharged hundreds of thousands of times.
The details of the double layer capacitor structure depend on the application and use of double layer capacitor. These materials may vary slightly because of manufacturer or specific application requirements. What all double-layer capacitors have in common is that they contain a positive electrode, a negative electrode, and a diaphragm between the two electrodes, with the electrolyte filling the pores separating the two electrodes and the diaphragm.
The double layer capacitor consists of a porous electrode material with elevated specific surface area, a porous battery diaphragm and an electrolyte. Diaphragm should meet the conditions of as strong as possible ion conductivity and as low as possible electron conductivity, typically for polypropylene film and alternative fiber structure of electronic insulation materials.
