Abstract
Garnet type electrolytes based on the sum formula Li7La3Zr2O12 (LLZO) have been identified as promising materials for solid state electrolytes with high ionic conductivity and electrochemical stability. Since the large-scale processing of thin and brittle ceramic sheets remains challenging and possible volume changes in a solid state battery require flexibility from the electrolyte/separator, the concept of composite electrolytes consisting of LLZO and polymer electrolyte based on poly(ethylene oxide) (PEO) has been explored by multiple research groups. The chapter is dedicated to introduce the concept of polymer and composite electrolytes and gives an overview of LLZO/PEO electrolytes investigated so far.
