| description | The invention relates to a calcium flaky Cu2S-Ni7S6 compound negative electrode material and a preparation method and application thereof.The preparation method comprises the following steps that foamed nickel, foamed copper and a copper sheet are placed in a thiourea mixed solution prepared from absolute ethyl alcohol and deionized water, through solvothermal reaction, the foamed nickel serves as a nickel source, the foamed copper and the copper sheet serve as copper sources, and the calcium flaky Cu2S-Ni7S6 compound negative electrode material is obtained under thiourea etching; nickel ions and copper ions enter the solution to be combined with sulfur ions, and the copper sheet loaded calcium sheet-shaped Cu2S-Ni7S6 compound is generated. The compound has a unique and novel three-dimensional layered composite structure, the lower layer is a calcium sheet-shaped nanobelt array with a rough surface, and the upper layer is in a coralline shape composed of a large number of particles.
