Abstract
An energy storage device includes a coated anode. The coated anode includes a metallic anode in contact with an electrically non-conductive star polymer coating. The star polymers in the star polymer coating include a core with at least 3 arms attached to the core. At least some of the arms of the star polymers have ionically conductive polar functional groups. The energy storage device further includes a cathode and an electrolyte in contact with both the cathode and the coated anode.
