Summary: We investigated the electrochemical properties of garnet-type Li6SrLa2Bi2O12 (LSLBO) ceramic electrolyte for all-solid-state Li-ion batteries. Hot pressing at 750 degrees C was applied for the densification of LSLBO and achieved a relative density of 94%. The hot-pressed LSLBO showed higher bulk and total ionic conductivity compared to sintered LSLBO reported in previous works. The results suggest the potential application of LSLBO as a catholyte in oxide-based all-solid-state batteries.
