A kind of ruthenium oxide-copper sulfide composite material, application and a kind of electrode sheet for supercapacitor

Abstract

The invention discloses a ruthenium oxide-copper sulfide composite material, which solves the disadvantages in the prior art that the ruthenium oxide is expensive and rarely used in industrial production. A ruthenium oxide-copper sulfide composite material, the preparation method of which comprises the following steps: (1) ultrasonically dissolving copper chloride hydrate in ethylene glycol, then adding thiourea to the above reaction system, and stirring for 0.5h to 1h; After stirring, hydrothermal reaction at 150°C to 200°C for 8h to 12h, suction filtration, water washing, alcohol washing, and drying at 150°C to 200°C for 24h to obtain copper sulfide nanomaterials; (2) hydrated ruthenium trichloride Dissolve in 40ml~60ml water, obtain the ruthenium trichloride solution of 10mg / ml~20mg / ml; (3); Add the copper sulfide nano material prepared in step (1) in the ruthenium trichloride solution prepared in step (2) , stirred for 0.5h to 1h; then hydrothermally reacted at 150°C to 200°C for 8h to 12h, suction filtered, washed with water, washed with alcohol, and dried at 150°C to 200°C for 24h to obtain a ruthenium oxide-copper sulfide composite material .

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. [...
