Abstract

The invention provides a lithium battery material powder demagnetization device. The lithium battery material powder demagnetization device comprises a barrel body, a material separating apparatus anda vibrating apparatus. A first magnetic pole and a second magnetic pole are symmetrically arranged on the two sides of the barrel body, the central connecting line of the first magnetic pole and thesecond magnetic pole is parallel to the horizontal plane, a plane which penetrates through the axis of the barrel body and is perpendicular to the central connecting line is defined as a first plane,at least two magnetic material absorbing layers are arranged inside the barrel body, each magnetic material absorbing layer comprises 2k first metal bars which are arranged in the direction from the first magnetic pole to the second magnetic pole horizontally in sequence, the 2k first metal bars are symmetrically arranged using the first plane as a symmetric plane, gaps which are used for lithiumbattery material powder to pass are formed between the adjacent first metal bars, the first metal bars are made from metal magnetic materials, the first metal bars comprise first lateral sides and second lateral sides, the second lateral sides of the first metal bars all face the first plane, and the first lateral sides are all back to the first plane; and the polarity of the first magnetic pole and the polarity of the second magnetic pole are opposite.

Description

technical field [0001] The invention belongs to the technical field of magnetic separation, and relates to a demagnetization device for lithium battery material powder, in particular to a magnetic separation device for ultrafine powder particles of lithium battery material. Background technique [0002] As we all know, positive and negative electrode materials are one of the key core materials of lithium-ion batteries, and their performance directly affects the performance indicators of lithium-ion batteries. Currently, the positive electrode materials of lithium-ion batteries that have been marketed include lithium cobalt oxide, lithium manganese oxide, Products such as lithium iron phosphate and ternary materials. Compared with other raw materials of lithium-ion batteries, the types of positive and negative electrode materials are more diversified, the production process is more complicated, and the risk of quality failure is greater, so the requirements for its quality ma...
