Manufacturers produce lithium electronic battery separators

The lithium electronic battery separator is an indispensable and important component of the lithium-ion battery. It is located between the positive and negative electrodes inside the battery. Its main function is to ensure the passage of lithium ions while hindering the transmission of electrons.

The main function of the battery separator is to separate the positive and negative plates in the battery to prevent direct contact between the positive and negative plates to cause a short circuit. At the same time, because there are a large number of micropores in the separator, the positive and negative ions in the battery can pass through the micropores. The electrons pass through freely and migrate between the positive and negative plates to form an internal conductive circuit of the battery, while the electrons migrate between the positive and negative electrodes through the external circuit to form a current for use by electrical equipment.

Lithium electronic battery separators are mainly made by mechanical stretching of ptfe materials.

PTFE is a highly crystalline polymer polymerized with tetrafluoroethylene as a monomer.

It is a white waxy thermoplastic similar to polyethylene (PE).

It has excellent high temperature resistance and low temperature resistance. The melting point is 327 degrees Celsius and the decomposition temperature is 415 degrees Celsius. It can be used for a long time in the range of 200 to 260 degrees Celsius.

At the same time, the material is highly hydrophobic, has non-adhesiveness, corrosion resistance, thermal stability and good mechanical properties, so it can be washed with water to restore its performance and be reused, greatly extending its service life and saving costs.

The lithium electronic battery separators produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of the PTFE membrane; using American Imported production and testing instruments are used to test the quality of PTFE film, and have also passed international SGS testing and certification, as well as ISI testing and certification.
