摘      要：Halide electrolytes in solid-state batteries with excellent oxidative stability and high ionic conductivity have been well reported ***,the high-cost rare-earth elements and long duration of highrotation milling procure are the major ***,we have successfully synthesized the low cost Li_(2.25)Zr_(0.75)Fe_(0.25)Cl_(6)electrolyte consisting of abundant elements with comparable Li-ion conductivity in a short milling duration of 4 *** transition of the annealed sample was also carefully *** Ni_(0.6)Co_(0.2)Mn_(0.2)O_(2)/Li_(2.25)Zr_(0.75)Fe_(0.25)Cl_(6)/Li_(5.5)PS_(4.5)Cl_(1.5)/In-Li batteries using different halide electrolytes were constructed and cycled at different voltage ***-state battery using Li_(2.25)Zr_(0.75)Fe_(0.25)Cl_(6)electrolyte obtained from long milling duration delivers higher discharge capacities and superior capacity retention than shorter milling time between 3.0 and 4.3 *** delivers much higher discharge capacity when cycled at elevated temperature(60℃)and suffers fast capacity degradation when the upper cut-off voltage increases to 4.5 V at the same current *** work provides an efficiency synthesis strategy for halide solid electrolyte and studies its applications in all-solid-state batteries in a wide temperature range.
