Transparent cubic garnet-type solid electrolyte of Al2O3-doped Li7La3Zr2O12

Transparent cubic garnet-type solid electrolyte of Al2O3-doped Li7La3Zr2O12 A transparent garnet-type lithium-ion conducting solid electrolyte of 1.0wt% Al2O3-doped Li7La3Zr2O12 (A-LLZ) was prepared using hot isostatic pressing (HIP). The A-LLZ pellet sintered at 1180°C for 36h was followed by HIP treatment at 127MPa and 1180°C under an Ar atmosphere. The bulk conductivity of the HIP treated A-LLZ was 9.9×10−4Scm−1 at 25°C. The Li/HIP treated A-LLZ/Li cell showed no short-circuit due to lithium dendrite formation at 0.5mAcm−2. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Solid State Ionics Elsevier

Abstract

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