Synthesis of solid polymer electrolyte
Solution casting was used to prepare polymer-salt electrolyte thin films containing nanofillers in polyethylene oxide matrix. In maximum conducting PEO:NaI polymer electrolyte homogenous solution, we have added different wt% ratios of nanoflake to develop nanofiller doped polymer electrolyte film. To remove solvent traces (if any) we have vacuum dried all films. Finally, we have fabricated a sandwitched structure maximum conducting nanofiller doped polymer electrolyte and r-Go as the active material.
