Embodiment Construction

[0114] This embodiment adopts a method for preparing a positive electrode material precursor, including:

[0115] Provide to reactor 100 the raw material that comprises the metal salt solution that is used to prepare cathode material precursor; Prompt raw material reaction to generate cathode material precursor, and continue to provide to reactor 100 during the growth process of cathode material precursor to ensure the growth of cathode material precursor to said metal salt solution to set requirements;

[0116] The solution in the reactor 100 is subjected to solid-liquid separation and filtration by the filter element located in the reactor 100 so that the liquid amount in the reactor 100 is maintained in the range required for the reaction; when the positive electrode material precursor grows to the set requirement, Drain it. After the extracted solution is output from the net liquid output port 11 of the filter, it is subjected to gas-liquid separation.

[0117] By adopti...

Abstract

The invention discloses a preparation method and system of a positive electrode material precursor. The preparation method of the positive electrode material precursor comprises the following steps of: supplying a raw material containing a metal salt solution for preparing the positive electrode material precursor to a reactor; promoting the raw material to react to generate a positive electrode material precursor, and continuing to provide the metal salt solution for ensuring that the positive electrode material precursor grows to meet a set requirement for the reactor in the growth process of the positive electrode material precursor; carrying out solid-liquid separation filtering on the solution in the reactor through a filtering element positioned in the reactor so as to maintain the liquid amount in the reactor in a range required by the reaction; and when the positive electrode material precursor grows to meet the set requirement, discharging the positive electrode material precursor.

Description

technical field [0001] The relevant part of the description of the present invention relates to the filter of the system that realizes the reaction and filtration concentration, specifically relates to the method of making the reaction raw materials undergo physical and / or chemical reactions and the reaction product is filtered and concentrated, especially relates to the preparation of the ternary material precursor The raw materials are reacted and the ternary material precursor is filtered and concentrated. Background technique [0002] In the processing flow that needs to react the reaction raw materials to obtain the reaction product first, and then filter and concentrate the reaction product, the reaction equipment used for reaction and the filter concentration equipment used for filter concentration are usually two independent of each other. different devices. For example, in a preparation process of a lithium-ion battery ternary material precursor, the reactor and th...
