| Abstract: | All-solid-state batteries with cathode composites containing high concentration of active materials are required to achieve higher energy densities. Here, a composite cathode containing up to 89 wt% of high-voltage cathode active material (LiNi1/3Mn1/3Co1/3O2) was prepared by covering this with a solution-derived solid electrolyte (argyrodite, Li6PS5Cl) and the incorporation of different content binder (ethyl cellulose). All-solid-state batteries were fabricated using 80Li(2)Sa (TM) 20P(2)S(5) (mol%) glass and indium metal as a solid electrolyte and anode, respectively. The all-solid-state battery with a composite cathode containing 0.5 wt% of ethyl cellulose showed an initial discharge capacity of 45 mAhg(-1) at 25 A degrees C and maintained 91.7% of the discharge capacity after ten cycles, around 30% higher than that obtained for the battery with the composite cathode without a binder. |
