[0002] Lithium-ion battery separator coating slurry is one of the essential raw materials for manufacturing lithium-ion batteries. Lithium-ion battery separator coating slurry is composed of solid and liquid. During the use of lithium-ion battery separator coating slurry , it is necessary to stir and mix the coating slurry of the lithium-ion battery diaphragm, so that the coating slurry of the lithium-ion battery diaphragm is evenly dispersed. The stirring and mixing structure design of the lithium-ion battery diaphragm coating slurry in the prior art is unreasonable, and the Diaphragm coating slurry often leads to poor manufacturing of lithium batteries due to uneven solid-liquid mixing; in addition, lithium-ion battery diaphragm coating slurry often causes denaturation of lithium-ion battery diaphragm coating slurry due to standing solid-liquid separation, which cannot ensure lithium battery life. Stability of performance of ion battery separator coating slurry
