Abstract

A solid-state Li-ion battery cell includes an anode, a cathode, and a solid electrolyte interposed between the anode and the cathode. The anode includes anode active material and the cathode includes cathode active material. The solid electrolyte includes a melt-infiltration solid electrolyte composition infiltrated in at least a portion of the anode and at least a portion of the cathode. The melt-infiltration solid electrolyte composition includes a lithium halide compound selected from: LiMgAlCl, LiMgCl, LiCl, and LiAlCl. The solid electrolyte is characterized by a melting temperature of approximately 200° C. or less (e.g., in some designs, approximately 150° C. to approximately 156° C.).
