Abstract

The invention discloses a method for manufacturing a supercapacitor, which comprises the following steps: (1) winding an electrode core; (2) welding; (3) vacuum heat treatment; (4) shelling and rolling groove; (5) liquid injection Finally, add a sealing rubber stopper and seal the injection hole. The method solves the problems that the existing manufacturing method has high requirements on the production environment, low production efficiency and potential safety hazards for the operators. Low water and oxygen content requirements; through multiple ultrasonic treatments and nitrogen replacement of oxygen and water in the supercapacitor monomer, it not only meets the ultra-low water and oxygen content requirements of supercapacitors, but also reduces its large leakage and 1000h life test. The volatility of each test index.

Description

technical field [0001] The invention relates to the field of supercapacitors, in particular to a method for manufacturing a wound supercapacitor. Background technique [0002] Supercapacitors are green and environmentally friendly new energy storage components. With the advantages of environmental protection, high power density, and long service life, they are used in the start and stop of automobiles, hybrid vehicles, pure electric vehicles, wind power pitch, forklift power, and elevators. , Intelligent three watches, military industry, aerospace and other emerging fields have a wide range of applications. [0003] Due to its complex structure and many production processes, supercapacitors have extremely high requirements for water and oxygen content in the final product, especially for water. Therefore, the current process is to invest a huge amount of money to control the production environment. The moisture in the production environment is controlled to an extremely low...
