Abstract
Polyurethane was used as matrix for polymer electrolytes with liquid electrolyte consist of organic solvent as ethylene carbonate(EC), propylene carbonate(PC), and tetraethylene glycol dimethylether(TG) and 1M $LiCF_3SO_3$, which has high mechanical strength and porosity. Electrochemical properties fur polyurethane electrolytes with various liquid electrolytes were evaluated. The amount of immersed liquid electrolyte for TG with 1M $LiCF_3SO_3$ was increased to about $750\%$ by weight, and initial discharge capacity and cycle performance was better than others. Ionic conductivity for TG/EC(v/v,1:1) and PC/EC(v/v, 1:1) with 1M $LiCF_3SO_3$ was about $3.15\times10^{-3} S/cm, \;3.18\times10^{-3}S/cm$
