A kind of preparation method of intermittent nickel-cobalt-aluminum precursor

Abstract

The invention relates to the technical field of precursor preparation, and discloses a batch-type nickel-cobalt-aluminum precursor preparation method, including a reaction kettle, one side of the top of the reaction kettle is provided with a first feeding pipe, and the other side of the top of the reaction kettle One side is provided with a second feed pipe, the top of the reaction kettle is provided with a fixed frame, and the inside of the fixed frame is provided with a driving motor, and one end of the output shaft of the driving motor is provided with a rotating rod. The bottom of the fixed block is provided with a fixed block, and the bottom of the fixed block is provided with a support frame, the bottom of the inner cavity of the support frame is provided with a rotating disc, and one side of the top of the rotating disc is provided with a limit sleeve. The intermittent nickel-cobalt-aluminum precursor preparation method, the preparation method, through the mutual cooperation between the central controller, the sealing plate and the sieve plate, facilitates better solid-liquid separation of the solvent and particles inside the reactor, thereby solving the problem of In addition to separating the solvent and particles in the reactor, it needs to be carried out through other equipment, which improves the efficiency of solid-liquid separation.

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...
