Abstract

A transparent garnet-type lithium-ion conducting solid electrolyte of 1.0 wt% Al2O3-doped Li7La3Zr2O12 (A-LLZ) was prepared using hot isostatic pressing (HIP). The A-LLZ pellet sintered at 1180°C for 36 h was followed by HIP treatment at 127 MPa and 1180°C under an Ar atmosphere. The bulk conductivity of the HIP treated A-LLZ was 9.9 × 10- 4 S cm- 1 at 25°C. The Li/HIP treated A-LLZ/Li cell showed no short-circuit due to lithium dendrite formation at 0.5 mA cm- 2.
