Teflon proton membrane is an indispensable part of the composition of lithium batteries. It plays a key role in the safety, cycle stability, capacity retention and heat resistance of the battery.
From an academic point of view, the separator is inert in the battery, that is, the separator is not a necessary component of the battery, but is only a requirement for the industrial production of the battery.
The existence of the separator must first ensure that it cannot deteriorate the electrochemical performance of the battery, which is mainly reflected in the internal resistance.
The ratio between the resistivity of the separator containing the electrolyte and the resistivity of the electrolyte itself is called the MacMullin number.
Teflon proton membrane is mainly made by mechanical stretching of ptfe material.
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.
It is a high-tech enterprise focusing on the R&D, production and sales of Teflon proton membranes. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we produce The products are produced using imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
And we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
