Abstract

The invention discloses a manufacturing method of a supercapacitor and a welding method of the supercapacitor. The manufacturing method of the supercapacitor comprises the steps: obtaining a winding core through a winding process; providing an insulating cover plate, wherein a first conductive terminal and a second conductive terminal which are insulated from each other are arranged on the insulating cover plate; providing a metal shell, wherein an opening is formed in one end of the metal shell, and an inner cavity is formed in the metal shell; putting the winding core into the inner cavity of the metal shell; fixing the insulating cover plate to the shell; electrically connecting one end, close to the end plate, of the winding core with the metal shell; and providing a metal cover plate, placing the metal cover plate at the side, far away from the roll core, of the insulating cover plate, and electrically connecting the metal cover plate with the second conductive terminal and the metal shell. In the supercapacitor manufactured by the manufacturing method, a positive terminal and a negative terminal of the supercapacitor can be arranged in the same side, so that connection is convenient, and use is more flexible.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a method for manufacturing a supercapacitor and a welding method for a supercapacitor. Background technique [0002] Supercapacitors have excellent power characteristics, can withstand instantaneous high current charge and discharge, and are widely used in starting devices. In order to obtain better power performance, supercapacitors are required to have a smaller internal resistance. Among them, the capacitance structure of the internal cell cross-layer winding type is currently commonly used with a low internal resistance structure. [0003] However, the current capacitor structure of the internal electric core cross-layer wound type needs to lead out the positive terminal and the negative terminal on both sides of the capacitor, and the external device needs to be connected to both sides of the capacitor, and the connection is more complicated. Those skilled in the art hope...
