Description

technical field

[0001] The invention belongs to the technical field of supercapacitor preparation, and in particular relates to a supercapacitor that can be easily disassembled and recycled, a manufacturing method and a disassembly and recycling method. Background technique

[0002] Electric double-layer supercapacitors have the advantages of fast charging, long life, and high power density. They play an irreplaceable role in recovering energy from starting and braking of heavy locomotives and large machinery. The recent development trend is to use carbon nanomaterials as electrode materials to replace activated carbon electrode materials, and to operate at higher voltage (3V) in order to obtain higher energy density to expand the application field of supercapacitors.

[0003] The most traditional capacitor structure is that the electrode material is attached to the metal plate current collector, then the tabs are welded, separated by a diaphragm, and electrolyte is injected...
