Description

technical field [0001] The invention belongs to the technical field of electrochemical capacitors, in particular to a ruthenium oxide-copper sulfide composite material, its application and an electrode sheet for a supercapacitor. Background technique [0002] Supercapacitor is a new type of energy device between secondary batteries and traditional physical capacitors. Compared with traditional capacitors, supercapacitors store more than 10 times the energy density of traditional capacitors; compared with batteries, they have higher Power density, high charge and discharge efficiency, long cycle life and other advantages. Therefore, it is widely used in the field of electric vehicles as an energy storage device, and can also play an important role in aerospace and national defense construction as a high pulse current generator. At present, the electrode materials for supercapacitors mainly include carbon materials, metal oxide materials and conductive polymer materials. [...
