celgard 3501

We have a deep collaboration with Celgard to use the Celgard 3501, a fine example of Celgard's surfactant coated separators, in our products.

High alkali resistance, high ionic passage rate, high electrical resistance, and low-temperature stability provide unlimited possibilities for LTZAB.
