[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium batteries need to use ball mills to process raw materials during production. Ball mills are also called ball mills. They are a common equipment for grinding or grinding. The materials are crushed and mixed by the impact of the falling grinding body and the grinding effect of the grinding body and the inner wall of the ball mill.
