Abstract
Abstract Solid polymer electrolytes have been prepared consisting of magnesium or zinc trifluoromethanesulfonates [Mg(CF 3 SO 3 ) 2 or Zn(CF 3 SO 3 ) 2 ], ethylene carbonate, and propylene carbonate included in a photo-crosslinked polymer of poly-(ethylene glycol) diacrylate and reinforced by a porous polypropylene membrane. Their conductivities are 1.7×10 −4 S cm −1 at 1 mol% for Mg(CF 3 SO 3 ) 2 , 2.1×10 −4 S cm −1 at 4 mol% for Zn(CF 3 SO 3 ) 2 , and 4.3×10 −4 S cm −1 at 12 mol% for LiCF 3 SO 3 systems at 25°C. Their Arrhenius plots are almost linear between −5 and 55°C with 15–25 kJ mol −1 activation energy for conduction.
