Abstract
A self-protecting functional separator for a battery cell is provided. The self-protecting functional separator includes a polymer substrate including a first primary surface and a second primary surface. The self-protecting functional separator further includes a functional layer applied to the first primary surface. The functional layer including a mixture includes a first piezoelectric material including a single crystal-type material and a second piezoelectric material.
