Description

Technical Field

[0001] This invention relates to the field of electrical engineering technology, and in particular to a high-voltage resistant supercapacitor electrode. Background Technology

[0002] Supercapacitors are a type of power source that falls between traditional capacitors and batteries. They rely on redox pseudocapacitance and double-layer capacitance to charge and store electrical energy. Supercapacitors are composed of electrode plates, separators, and other materials, which ensure that the supercapacitor can withstand high voltage and that the operating voltage of the supercapacitor is stable.

[0003] According to CN201811147054.5, this invention relates to a supercapacitor electrode, comprising an insertion electrode segment extending into the capacitor, a fixed electrode segment at one end of the insertion electrode segment, a locking electrode segment at one end of the fixed electrode segment, and an external connection electrode segment at one end of the locking electrode segment. The insertion electrode segment and the fixed electrode segment together form an "L"-shaped folded plate, and the locking electrode segment is generally "U"-shaped. The insertion electrode segment is inserted into the capacitor to initially fix the electrode to the capacitor, and the locking electrode segment is positioned between the capacitor cover and the housing to further fix the electrode and prevent the electrode from moving. Furthermore, the fixed electrode segment is fixed to the cover of the electrode with bolts, effectively positioning the electrode on the housing and preventing displacement of the electrode during epoxy resin potting, thus ensuring product quality.
