A Raney Ni/NiCl2 composite positive electrode material and a preparing method thereof

A Raney Ni/NiCl2 composite positive electrode material and a preparing method thereof are provided. The method includes 1) a step of weighing Raney Ni, subjecting the Raney Ni to water replacement and washing with absolute alcohol, and then adding the Raney Ni into a container containing deionized water; 2) a step of adding NaClO and a surfactant into a beaker at 40-80 DEG C, stirring the mixture, performing suction filtration, then washing a product with absolute alcohol and deionized water, putting the product into a vacuum drying oven and drying the product to obtain a precursor; and 3) a step of grinding and mixing the precursor and NH4Cl, then calcinating the mixture in a muffle furnace, naturally cooling a product to room temperature, and ball-milling and crushing a block product to obtain the composite positive electrode material. The composite positive electrode material prepared by the method has a large specific surface area and a low resistivity. 本发明提供Raney Ni/NiCl复合正极材料及其制备方法，本发明提供的Raney Ni/NiCl复合
