Embodiment 1

[0028] Example 1 A preparation method for a graphite oxide-cadmium sulfide compound applied to an electrode material, the preparation steps are:

[0029] (1) Preparation of graphite oxide: graphite powder was used as raw material to prepare graphite oxide by the Hume method, washed with secondary water centrifuge and placed in a vacuum drying oven at 60 °C for 24 h to obtain dry graphite oxide;

[0030] (2) Preparation of microemulsion: Add 20 mg of graphite oxide, 30 mL of cyclohexane, 4 mL of Triton X-10 (OP), 0.4 g of cetyltrimethyl ammonium bromide (CTAB) and 2 mL CdCl 2 solution, and then vigorously stirred for 15 min to obtain liquid A. CdCl in A 2 Change to Na 2 S, and then vigorously stirred for 15 min to obtain liquid B. After mixing A / B, stir slightly to obtain an inverse microemulsion system;

[0031] (3) Preparation of graphite oxide-cadmium sulfide composites by hydrothermal method: transfer the microemulsion into a 100 mL hydrothermal kettle, and finall...

Description

technical field [0001] The invention relates to the technical field of inorganic synthesis of electrode materials, in particular to a method for preparing graphite oxide-cadmium sulfide composites applied to electrode materials. Background technique [0002] Energy is the material basis for the existence and development of human society and the driving force for the operation of the social and economic system. In the new century, our country is facing the problems of energy supply security and economic security. Under such a severe energy situation, various new energy sources need to be developed urgently. Among them, supercapacitors have attracted extensive attention of researchers at home and abroad because of their excellent pulse charge and discharge performance and large-capacity energy storage performance that traditional capacitors do not have. Including metal sulfides with excellent electrochemical properties, metal oxides and their composite materials are all rega...
