Working principle: The aluminum electrolytic capacitor is composed of an electrolyte and an aluminum foil capacitor. The electrolyte is an alkaline liquid solution which can be thickened by sticking a binder with a certain specific gravity. The aluminum foil that forms the capacitor is mainly composed of a cathode aluminum foil, an anode aluminum foil and a separator.

The cathode aluminum foil and the anode aluminum foil respectively connect and form a large area of contact with the electronic liquid holding member of the capacitor shell after being wound together multiple layers with adhesive tape and then stretched out straight, and a certain distance is maintained between them, forming an insulation layer. The separator is mainly to separate the cathode aluminum foil and the anode aluminum foil, dividing space between them to form a double-layer structure with the dielectric membrane as the insulation layer.

When the aluminum electrolytic capacitor works, the cathode and anode are both connected to the electrical device and the positive and negative terminals of the direct current. The anode aluminum foil and the separator are composed of a double-layer structure of double-layer aluminum electrolysis, which attracts mobile ions around the double-layer capacitance after applying the direct current, thereby forming a dielectric thin film on the anode surface. The dielectric thin film is the dielectric layer, and this composition forms an electrostatic capacitance to accumulate the electric charge. When the direct current is stopped, the dielectric thin film still exists, reject the current from passing through, and form electric insulation between both ends and peripheral circuits, the above is the basic working principle of the aluminum electrolytic capacitor.
