Abstract:The results of preliminary studies of a new polymer electrolyte based on poly(lithium acrylate)-PAALi, with low-melting-point eutectic lithium salts consisted of lithium nitrate and lithium acetate were described. The solution polymerization of PAALi was prepared from crylic acid and LiOH under optimum conditions of initiator concentration 0.2%(w%), monomer concentration 16%(w%), polymerization time 2 h, polymerization temperature 80℃. The ionic conductivity of PAALi was measured at range of 10~(-9)~10~(-10... |
