Title:
PROCESSING METHOD AND PRODUCTION LINE FOR LITHIUM BATTERY POSITIVE ELECTRODE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/050130
Kind Code:
A1
Abstract:
The present invention relates to a processing method and a production line for a lithium battery positive electrode material. The processing method for lithium battery positive electrode material comprises the following steps: (1) after uniformly mixing positive electrode material powder, directionally conveying the positive electrode material powder to a molding system by means of a conveyor belt inclined downwards; (2) performing high-speed granulation or briquetting on the positive electrode material powder in the molding system to form a spheronized positive electrode material or a block-shaped positive electrode material; (3) directionally conveying the spheronized positive electrode material or the block-shaped positive electrode material to a calcination system by means of the conveyor belt inclined downwards to be calcined and cooled; (4) continuing to convey the calcined and cooled spheronized positive electrode material to a crusher by means of the conveyor belt, to be crushed and then directly into a material collection vehicle for collection. The production line disclosed in the present invention is environmentally friendly, simple and efficient. When the production of the positive electrode material of the lithium battery is carried out using the present production line, continuous mass production of the lithium battery positive electrode material can be achieved, and the production line has great industrialization prospects.
