Method for preparing intermittent nickel, cobalt and aluminum precursors

Abstract

The invention relates to the technical field of precursor preparation, and discloses a method for preparing intermittent nickel, cobalt and aluminum precursors. The method is implemented by a reactionkettle. A first feed pipe is arranged on one side of the top of the reaction kettle, a second feed pipe is arranged on the other side of the top of the reaction kettle, a fixing frame is arranged onthe top of the reaction kettle, a driving motor is arranged inside the fixing frame, a rotary rod is arranged at an end of an output shaft of the driving motor, fixing blocks are arranged at the bottom of a side of the reaction kettle, a support frame is arranged at the bottoms of the fixing blocks, a rotary disc is arranged at the bottom of an inner cavity of the support frame, and limit sleevesare arranged on a side of the top of the rotary disc. The method for preparing the intermittent nickel, cobalt and aluminum precursors has the advantages that a center controller, a sealing plate anda sieve plate are matched with one another, accordingly, solid-liquid separation can be conveniently effectively carried out on solvents and particles inside the reaction kettle, the problem that existing solvents and existing particles in existing reaction kettles need to be separated from one another by other equipment can be solved by the aid of the method, and the solid-liquid separation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of precursor preparation, in particular to a batch-type method for preparing a nickel-cobalt-aluminum precursor. Background technique [0002] The nickel-cobalt-aluminum precursor needs to go through a multi-stage process in the preparation process, mainly including ingredients, reaction, washing and drying, etc. Nowadays, when the reaction kettle is used to prepare the nickel-cobalt-aluminum precursor, the neutralization reaction efficiency is low. It is easy to produce more particles, which will affect the final nickel-cobalt-aluminum precursor material. At the same time, after the reaction is over, the product needs to be separated from the solid and liquid by other equipment, adding a certain process, making the reaction efficiency of the nickel-cobalt-aluminum precursor low. . Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies raised by the above-men...
