Abstract

The invention discloses a magnetic adsorption structure and a conductive slurry filtering device. The magnetic adsorption structure comprises a magnetic bar and a column body. One side of the longitudinal central plane of the magnetic bar is an N pole, and the other side of the longitudinal central plane of the magnetic bar is an S pole. The column body comprises ferromagnetic material blocks and non-ferromagnetic material blocks which are fixedly connected, a hole for the magnetic bar to penetrate through is formed in the column body, and the ferromagnetic material blocks and the non-ferromagnetic material blocks are alternately arranged in the circumferential direction of the hole. Wherein the magnetic bar is inserted into the hole and is rotationally connected with the hole, so that the longitudinal central plane can rotate. Compared with the prior art, the removal efficiency of ferromagnetic impurities can be improved, so that the product performance of the lithium battery is improved.

Description

technical field [0001] The invention relates to the technical field of conductive paste, in particular to a magnetic adsorption structure and a conductive paste filter device. Background technique [0002] Carbon nanotube conductive paste (hereinafter referred to as conductive paste) is a new type of high-efficiency conductive agent used in lithium batteries, which can replace traditional conductive agents such as conductive graphite, conductive carbon black, and conductive carbon fiber. With the application of conductive paste in lithium batteries more and more widely, the requirements for the quality of conductive paste products are becoming more and more stringent. The conductive paste usually contains various metal particles and non-metal particle impurities. When the impurity content is high, it will have a great impact on the product performance of the lithium battery, such as poor battery K value, battery micro-short circuit and battery self-discharge. [0003] In th...
