Abstract

The invention discloses a tin antimony oxide / holmium oxide / indium tin oxide electrode material for a supercapacitor and a preparation method of the tin antimony oxide / holmium oxide / indium tin oxide electrode material. The preparation method comprises the following steps: 1) soaking a substrate in diluted hydrochloric acid, repeatedly cleaning the substrate, and drying the substrate at constant temperature; 2) mixing and dissolving tin antimony oxide, holmium oxide and polyvinylidene fluoride in a solvent to obtain a solution A, mixing and dissolving indium tin oxide, holmium oxide and polyvinylidene fluoride in a solvent to obtain a solution B, and ultrasonically stripping and dispersing the solution A and the solution B under the ultrasonic action; (3) injecting the solution A on the substrate for several times, performing drying after injecting, injecting the solution B on a primary electrode material for several times, and performing drying to obtain the composite electrode material. The composite electrode material has excellent electrochemical performances, the capacitance can still remain more than 79% of the original capacitance after 10000 cycles, and the coulombic efficiency is still more than 98%.

Description

technical field [0001] The invention belongs to the technical field of super capacitors, in particular to a composite electrode material of tin antimony oxide / holmium oxide / indium tin oxide for super capacitors and a preparation method thereof. [0002] technical background [0003] As a new type of energy storage device, supercapacitor has the advantages of green, environmental protection, short charging time, high power density, good cycle performance and long service life. Hybrid "Super Batteries". Supercapacitors are divided into electric double layer capacitors, pseudocapacitors and hybrid capacitors according to the different forms of energy storage. Compared with batteries, although supercapacitors have higher power density, their energy density is lower than that of silicon, lithium and other batteries, which affects their performance. There are mainly electrode materials, electrolytes and separators, among which the primary factor limiting its performance is the ele...
