All-solid-state thin-film batteries based on lithium phosphorus oxynitrides

Abstract Lithium phosphorus oxygen nitrogen (LiPON) as solid electrolyte discovered by Bates et al in the 1990s is an important part of all-solid-state thin-film battery (ASSTFB) due to its wide electrochemical stability window and negligible low electronic conductivity. However, ionic conductivity LiPON about 2 × 10 −6 S cm −1 at room temperature much lower than that other types electrolytes, which seriously limits application ASSTFBs. This review summarizes research progress ASSTFBs based on LiPON, solid-state LiPON-derivatives with adjustable chemical compositions amorphous structure for improvement stability, critical interface issues between electrodes, preparation methods LiPON. helpful people understand characteristics various The key be addressed concern how develop films high high-quality engineering well large-scale technology, so realize practical highly integrated
