Solid-state batteries with high energy density and safety are promising next-generation battery systems. However, lithium oxide and lithium sulfide electrolytes suffer low ionic conductivity and poor electrochemical stability, respectively. Lithium halide solid electrolyte shows high conductivity and good compatibility with the pristine high-voltage cathode but limited applications due to the high price of rare metal. Zr-based lithium halides with low cost and high stability possess great potential. Herein, a small amount of In is introduced in LiZrCl to synthesize LiZrInCl electrolytes with a high room temperature Li-ion conductivity of 1.08 mS/cm. Solid-state batteries using LiZrInCl/LiPSCl bilayer solid electrolytes combined with Li-In anode and pristine LiNiMnCoO cathode deliver high initial discharge capacities under different cut-off voltages. This work provides an effective strategy for enhancing the conductivity of LiZrCl electrolytes, promoting their applications in solid-state batteries.
