Lithium-ion battery separator, in the structure of lithium battery, the separator is one of the key inner components. For the lithium battery series, since the electrolyte is an organic solvent system, a diaphragm material resistant to organic solvents is required, and a high-strength thin-film polyolefin porous film is generally used. 1. Performance of lithium-ion battery separator products Since the performance of the lithium-ion battery separator determines the key characteristics of the lithium-ion battery, such as capacity, cycle performance, and charge-discharge current density, the separator is required to have appropriate thickness, ion transmission rate, pore size and porosity, and sufficient chemical stability. performance, thermal stability and mechanical stability. Lithium-ion battery separator has a large number of zigzag through micropores, which can ensure the free passage of electrolyte ions to form a charge-discharge circuit; when the battery is overcha...
