Abstract
All Solid State Lithium Ion Batteries (ASS-LIB) have been attracting great attention due to their high temperature stability, energy density and safety. Cubic Li7La3Zr2O12 (LLZO) ceramic electrolyte is one of the most studied solid electrolyte because of its exceptionally high chemical stability against Li metal, air and moisture, thermal stability and very competitive ionic conductivity. In order to stabilize cubic LLZO, relatively high temperatures are required. On the other hand, it's possible to decrease sintering temperature and time with a stabilizer addition. In this study, 20
