Background
Lithium battery refers to a battery containing Lithium including metallic Lithium, lithium alloy and Lithium ion, lithium polymer in electrochemical system. Lithium batteries can be broadly classified into two types: lithium metal batteries and lithium ion batteries. A lithium battery is a type of rechargeable battery that mainly operates by movement of lithium ions between a positive electrode and a negative electrode. Batteries generally using a material containing lithium as an electrode are representative of modern high-performance batteries. With the development of new energy greatly promoted by the state, the demand of various industries on lithium ion power batteries is increasing day by day, and a battery cell in a composition structure of the lithium ion power battery is a core component of the lithium ion power battery, and the battery cell is generally formed by mutually overlapping positive and negative pole pieces in a staggered manner. The battery core composition structure comprises a plurality of positive and negative pole pieces which are staggered and overlapped up and down, and the positive and negative pole pieces are isolated and insulated by a diaphragm.
