Lithium battery separator is one of the key inner components of lithium battery. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety of the battery. The separator with excellent performance plays an important role in improving the overall performance of the battery.
The main performance requirements of lithium-ion battery diaphragm include: thickness uniformity, mechanical properties (including tensile strength and puncture resistance), air permeability, physical and chemical properties (including wettability, chemical stability, thermal stability, and safety).
According to different physical and chemical characteristics, lithium battery separators can be divided into woven membrane, non-woven membrane (non-woven fabric), microporous membrane, composite membrane, diaphragm paper, rolled membrane, etc.
Polyolefin materials have excellent mechanical properties, chemical stability and relatively cheap characteristics. Therefore, polyethylene, polypropylene and other polyolefin microporous membranes have been used as lithium battery separators at the initial stage of research and development of lithium batteries. In recent years, there have been studies on the preparation of lithium battery separators with other materials, such as the preparation of lithium battery separators with polyvinylidene fluoride (PVDF) as bulk polymer by phase inversion method, and the research on cellulose composite membranes as lithium battery separator materials.
