Lithium-ion battery separator, in the structure of lithium batteries, the separator is one of the key inner components. For lithium battery series, because the electrolyte is an organic solvent system, it is necessary to have a diaphragm material resistant to organic solvents, and a high-strength thin-film polyolefin porous membrane is generally used.

The performance of the separator determines the interface structure and internal resistance of the battery, and directly affects the capacity, cycle and safety performance of the battery. The excellent separator plays an important role in improving the overall performance of the battery. The main function of the separator is to separate the positive and negative electrodes of the battery to prevent the two poles from contacting and short-circuiting. In addition, it also has the function of allowing electrolyte ions to pass. The material of the separator is non-conductive, and its physical and chemical properties have a great influence on the performance of the battery. Different types of batteries use different separators. For the lithium battery series, since the electrolyte is an organic solvent system, it is necessary to have a separator material resistant to organic solvents, and a polyolefin porous film with high strength is generally used.

According to different physical and chemical properties, lithium battery separator materials can be divided into: woven membrane, non-woven membrane (non-woven), microporous membrane, composite membrane, separator paper, rolled membrane and other categories. Polyolefin materials have excellent mechanical properties, chemical stability and relatively inexpensive characteristics, so polyethylene, polypropylene and other polyolefin microporous membranes have been used as lithium battery separators in the early stages of lithium battery research and development.

As a key component of lithium batteries, the industry has significantly benefited from the booming power battery market and energy storage market in recent years, showing a rapid growth trend, and under the premise that the global green economy wave will not have a major turn in the short term, this growth has a certain degree of sustainability.
