Embodiment Construction
[0012] The method for preparing nickel-based battery materials according to the present invention includes the following steps:
[0013] (1) Put CeO 2 , NiO, SnO 2 The powder is mixed with the binder, wet-milled in a ball mill for 2 hours, taken out and dried and pressed into a disc at 45 MPa, drilled in the middle, and sintered at 850-1250°C for 5 hours;
[0014] (2) The sintered sheet is suspended on the iron-chromium-aluminum wire as the cathode, and the periphery is wrapped with the iron-chromium-aluminum wire to increase the current density and speed up the reaction rate; add CaCl 2 Slowly heat up to 450°C in a muffle furnace and keep it for 5 hours; place it in an alumina crucible after cooling and place it at the bottom of the reactor;
[0015] (3) During the heating process of the electrolysis furnace, the cathode and graphite carbon rods are suspended above the molten salt for preheating, and argon gas is introduced at the same time; the temperature of the molten salt reaches...
