Solid state polymeric battery fabrication of hot-pressed nanocomposite polymer electrolyte

Abstract

Solid state polymeric battery based on newly synthesized Na⁺ ion conducting nano- composite polymer electrolyte (NCPE): 93 (70PEO: 30NaClO₄) + 7 SiO₂, has been fabricated in the cell configuration: Na-metal 93 (70PEO: 30NaClO₄) + 7 SiO₂ (C + I₂+NCPE). Na-metal and (C + I₂ + NCPE) in 1: 1:1 wt % ratios have been used as anode and cathode, respectively. The cell-potential discharge performances have been studied at different temperatures under different load conditions. To explain the ionic nature of the present NCPE, ionic transference number (t_ion) has also been calculated with the help of electrochemical cell-potential method.
