Abstract: An electrochemical cell has a cathode having a cathode current collector and a cathode active material, an anode having an anode current collector, lithium metal seed, and an anode cap on the lithium metal seed, 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. The anode cap and the polymer electrolyte lamination layer work together to produce densely plated lithium metal between the lithium metal seed and the anode cap with little or no external pressure.

Abstract: An all-solid-state battery cell has a cathode on which a cathode current collector is attached, a solid electrolyte deposited on the cathode opposite the cathode current collector, an anode comprising lithium deposited onto the solid electrolyte opposite the cathode, and an anode current collector bonded to the anode opposite the solid electrolyte with a bonding layer of a metal alloyed with the lithium.
