Abstract
A lithium ion battery separator includes a porous film of a polymeric chelating agent. The polymeric chelating agent includes a poly(undecylenyl-macrocycle), where the macrocycle is a chelating agent. A positive electrode includes a structure and a coating formed on a surface of the structure. The structure includes a lithium transition metal based active material, a binder, and a conductive carbon; and the coating includes a poly(undecylenyl-macrocycle), where the macrocycle is a chelating agent. The separator and/or positive electrode are suitable for use in a lithium ion battery.
