Polymethylmethacrylate (PMMA) based polymer gel electrolytes containing ammonium hexafluorophosphate (NH 4 PF 6 ) show conductivity higher than the corresponding liquid electrolytes. Nanodispersed gels prepared by the dispersion of fumed silica with particle size in the nanometer range to polymer gel electrolytes show conductivity of the order of 10 −2 S/cm at 25 °C. Two maxima...
Nonaqueous unimolar solutions of lithium perchlorate (LiClO 4 ) and lithium trifluoromethanesulfonate or triflate (LiCF 3 SO 3 ) in γ-butyrolactone (γBL) mixed in (a) 1:1 and (b) 3:2 volume ratios yield mixed salt electrolytes with good conductivity performance with σ 25 approaching 10 -2 S cm -1 . Addition of 10 wt.% of poly(methylmethacrylate)...
