Abstract
The invention provides a coating or film adapted to be arranged between a separator and at least one electrode of a rechargeable battery. The coating or film comprises a first material capable of forming a porous layer and allowing a passage of ions therethrough; wherein, in response to temperature change, the first material porous layer is adapted to substantially close pores in said first material porous layer to thereby substantially reduce or prevent further passage of ions through the first material.
