Abstract
A lithium-based battery separator includes a porous polymer membrane having opposed surfaces. A porous carbon coating is formed on one of the opposed surfaces of the porous polymer membrane. Polycations are incorporated in the porous carbon coating, in the porous polymer membrane, or in both the porous carbon coating and the porous polymer membrane.
