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...

Abstract

The invention relates to a method for preparing nickel-based battery material and belongs to the field of battery material preparation. The method is characterized by including: mixing CeO2, NiO and SnO2 powder into binder, preparing into a circular piece after wet grinding, and sintering; hanging the sintered piece on an iron-chromium-aluminum wire to serve as a cathode, and wrapping the periphery of the sintered piece with the iron-chromium-aluminum wire; slowly heating CaCl2 in a muffle furnace; placing into an alumina crucible after cooling, and placing at the bottom of a reactor; suspending the cathode and a graphite carbon bar above molten salt for preheating during the heating process of an electrolytic furnace, and feeding argon at the same time; inserting the cathode and the graphite carbon bar into the molten salt, and applying direct currents to start electrolysis; taking out a cathode product after the electrolysis is completed, washing with distilled water, and drying under normal temperature. The method for preparing the nickel-based battery material has the advantages that the process is improved, a method which directly electrolyzes metal oxide in the molten salt to prepare metal or alloy is used, process simpleness is achieved, and the method is easy in synthesizing control, low in production cost and free of pollution.

Description

Technical field [0001] The invention belongs to the field of battery material preparation, and particularly relates to a method for preparing nickel-based battery materials. Background technique [0002] In recent years, with the rapid economic development, communications, electric vehicles and other industries have also developed rapidly. Among them, batteries have been widely used. Among them, nickel-hydrogen batteries and lithium batteries are the most widely used, and nickel-based alloys such as LaNi 5 , CeNi 5 , Ni 3 Sn 2 Etc., are the more commonly used battery materials. LaNi 5 The industrial preparation method of type material is alloy melting method, Ni 3 Sn 2 Industrial preparation methods include electrodeposition, powder sintering and so on. However, these methods require the use of traditional methods to extract pure metals, which requires a long process, heavy pollution and high cost. Summary of the invention [0003] The present invention aims to solve the above-me...
