A dopant for a lithium-ion solid-state electrolyte (SSE) is disclosed for improving interfacial stability between halide-based SSEs and lithium-containing anodes. The dopant possesses a reduction potential higher than that of a central metal within the electrolyte framework. Therefore, during battery operation, the dopant is preferentially reduced, forming an interphase layer at the electrolyte-anode interface that suppresses reduction of the host electrolyte framework and mitigates interfacial degradation. The dopant thereby enables direct, stable contact between the halide SSE and the lithium-containing anode, without requiring a separate protective interlayer. In certain implementations, the dopant comprises FeCl3 incorporated into a Li3InCl6-based electrolyte, enabling stable operation with a lithium-indium alloy anode while maintaining the electrolyte's ionic conductivity.
