Abstract
One example of a lithium ion battery component is a lithium ion battery separator including a planar microporous polymer membrane and a chelating agent bonded to the planar microporous polymer membrane through a linking group. The chelating agent is bonded such that the permanent dipole moment of the chelating agent is oriented perpendicular to the plane of the planar microporous polymer membrane.
