Abstract
An anode for a lithium metal battery has a current collector formed of a flexible polymer substrate having an anode-facing surface, the polymer substrate formed of a polymer chemically compatible with lithium metal. A current pathway of a first conductive metal is embedded in the polymer substrate and has a terminal end extending from an end of the polymer substrate. Traces of a second conductive metal each have a current collecting portion at the anode-facing surface, the traces in electrical communication with the current pathway. Lithium metal is deposited onto the current collector.
