Solid-state polymer electrolyte for an energy storage device

Abstract

Aspects of the disclosure provide an energy storage device that can include a cathode, an anode, and a solid polymer electrolyte. The solid polymer electrolyte can include polyvinylidene fluoride (PVDF) and bis(trifluoro-methanesulfonyl)imide (LiTFSI). A mass content of the LiTFSI can be greater than a mass content of the PVDF. The solid polymer electrolyte can have a structural composition based on forming the solid polymer electrolyte using a solution comprising a solid content, comprising the PVDF and LiTFSI, and one or more solvents for dissolving the solid content, the solid content being approximately 0.19 or greater of the solution.
