Product Features

Chemical Resistance: PTFE battery separator has excellent chemical resistance, ensuring the stability and integrity of the battery when exposed to electrolytes, solvents and active materials.
Mechanical Strength: PTFE battery separator has sufficient mechanical strength to withstand handling during battery assembly and operation without tearing, puncturing or deformation.
Thermal Stability: PTFE battery separator has a high melting point and therefore has good thermal stability over a wide temperature range. It prevents thermal runaway and melting under extreme operating conditions.

Product Benefits

Our product helps prevent internal short circuits and thermal runaway by providing a stable, non-conductive barrier between the electrodes.
Our product facilitates efficient ion transport, which improves battery performance in terms of capacity, cycle stability and rate capability.
By minimizing electrode degradation and preventing irreversible reactions, our product helps extend the cycle life of lithium-ion batteries, making them suitable for long-term use in a variety of applications.
