 abstract={Al and Nb-doped Li7La3Zr2O12 (LLZO) and W-doped LLZO lithium ion conducting electrolyte samples were prepared and their H2O stability was investigated. The LLZO samples were exposed to 50% humidified air for 48 h. After H2O exposure, a cubic to tetragonal transformation occurred and acquired SEM images exhibited the presence of reaction phases at the grain boundaries of Al and Nb-LLZO. As a result, the lithium ion conductivity significantly decreased after H2O exposure. On the contrary, W-LLZO showed good stability against H2O. Although the cubic to tetragonal transformation was also observed in H2O-exposed W-LLZO, the decrease in lithium ion conductivity was found to be modest. No morphological changes of the W-LLZO samples were confirmed in the H2O-exposed W-LLZO samples.},
