Abstract
An electrochemical cell has a cathode having a cathode current collector and a cathode active material, an anode having an anode current collector and an anode active material comprising lithium metal, a liquid electrolyte, a separator between the cathode active material and the anode active material, and a polymer electrolyte lamination layer bonding the anode to the separator. The polymer electrolyte lamination layer is formulated using a crosslinked polymer, a lithium salt, a plasticizer, and an anode additive.
