Abstract

The invention discloses a high-energizing solid-liquid mixed aluminum electrolytic capacitor and a preparation method thereof. The capacitor comprises a shell, a capacitor core, a positive terminal and a negative terminal, the positive terminal and the negative terminal are connected with the capacitor core, the capacitor core is accommodated in the shell, the capacitor core comprises high-energizing electrode plates and electrolytic paper with electrolyte, the electrolytic paper is inserted between the two electrode plates and is wound into the capacitor core, a conductive polymer uniformly covers the high-energizing electrode plates. The capacitor is convenient to manufacture, and the technical problem that the conductive polymer dispersion liquid does not well impregnate the capacitor core is solved. The conductive polymer on the high-energizing electrode plates uniformly cover, and the solid-liquid mixed aluminum electrolytic capacitor has all excellent characteristics of an existing solid-state and liquid-state aluminum electrolytic capacitor, and moreover, improve the high-voltage, vibration, high frequency, high temperature, high ripple current resistance, long service lifeand low impedance performances of the capacitor.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a solid-liquid mixed aluminum electrolytic capacitor composed of highly energetic electrodes and a preparation method thereof. Background technique [0002] Aluminum electrolytic capacitors have two electrode plates, namely anode (positive) and cathode (negative), in which the anode is made of a specific metal aluminum, and the metal surface is electrochemically formed to be extremely thin and have unidirectional conductivity The aluminum oxide film is used as the dielectric, and the cathode usually uses light foil aluminum together with a liquid or solid electrolyte that can generate and repair the dielectric oxide film. Aluminum electrolytic capacitors are an energy storage electronic component composed of this special structure. [0003] The liquid aluminum electrolytic capacitor uses the liquid electrolyte to generate and repair the dielectric oxide film on the electrode s...
