主　　题：Solid electrolyte Li_(2)ZrCl_(6) Li-ion conductivity In-doping Solid-state battery 

摘      要：Solid-state batteries with high energy density and safety are promising next-generation battery ***,lithium oxide and lithium sulfide electrolytes suffer low ionic conductivity and poor electrochemical stability,*** 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 ***-based lithium halides with low cost and high stability possess great ***,a small amount of In^(3+)is introduced in Li_(2)ZrCl_(6) to synthesize Li_(2.25)Zr_(0.75)In_(0.25)Cl_(6) electrolytes with a high room temperature Li-ion conductivity of 1.08 mS/***-state batteries using Li_(2.25)Zr_(0.75)In_(0.25)Cl_(6)/Li_(5.5)PS_(4.5)Cl_(1.5) bilayer solid electrolytes combined with Li-In anode and pristine LiNi_(0.7)Mn_(0.2)Co_(0.1)O_(2) cathode deliver high initial discharge capacities under different cut-off *** work provides an effective strategy for enhancing the conductivity of Li2ZrCl6 electrolytes,promoting their applications in solid-state batteries.
