Abstract

The deposition and dissolution of Li at a Ni electrode coated with lithium phosphorus oxynitride (LiPON) thin film were investigated in lithium bis(trifluoromethylsulfonyl)amide-glyme solvate ionic liquid. The LiPON thin film was able to suppress the irreversible decomposition of the solvate ionic liquid. The cathodic deposition of Li and anodic dissolution of the deposited Li occurred on the Ni electrode through the LiPON thin film. These results suggest that the LiPON thin film plays a role as an artificial solid electrolyte interphase film between the Ni electrode and the solvate ionic liquid.
