Abstract
A lithium ion battery includes a positive electrode, a negative electrode, a microporous polymer separator disposed between the negative electrode and the positive electrode, and a polymer having a chelating agent tethered thereto. The polymer is incorporated into the lithium ion battery such that the chelating agent complexes with metal cations in a manner sufficient to not affect movement of lithium ions across the microporous polymer separator during operation of the lithium ion battery.
