Abstract

The invention discloses a supercapacitor electrode material. The supercapacitor electrode material is prepared by compounding a Ni layered double hydroxide generated by anodic oxidation and an in-situloaded Ni3S2 nano-particles with foamed nickel as a substrate. The supercapacitor electrode material and the preparation method have the advantages that a composite structure is prepared on the foamed nickel substrate by utilizing a hydrothermal and anodic oxidation method, and during a hydrothermal process, a molybdenum source is provided, a Ni-doped MoS2 hollow core ball is formed in the hydrothermal process, and amorphous NiMoS particles are synthesized at the moment, wherein Ni3S2 particles are loaded on the ball, and at the moment, the MoS2 hollow core ball plays a template role; duringthe follow-up anodic oxidation treatment process, Mo is dissolved, and Ni is fully oxidized to form Ni(OH)2, and finally, the composite structure is formed with the loaded Ni3S2 particles, and the composite structure is taken as the supercapacitor electrode material. The supercapacitor electrode material and the preparation method are low in preparation cost, good in repeatability, controllable instructure and beneficial to mass production.

Description

technical field [0001] The invention belongs to the field of supercapacitors, in particular to a supercapacitor electrode material and a preparation method thereof. Background technique [0002] With the continuous growth of population and the strong demand for energy for sustainable social development, the production, conversion and storage of energy have become the focus of attention in the world today. The current social energy is still highly dependent on fossil fuels. Although the development and utilization of renewable energy (such as solar energy, wind energy, and hydropower) has increased, the cost of obtaining these energy sources is still very high. In order to buffer large-scale energy supply and demand , people urgently need to develop a high-efficiency energy storage and conversion device to meet the needs of various applications, such as electric vehicles and small mobile devices such as mobile phones, notebook computers, and digital cameras. As a fast energy...
