Abstract

Lithium trifluoromethane-sulfonimide (LiTFSI) was dissolved in triethylene glycol dimethylethe (TGE) to form electrolyte. A novel hyperbranched PEU (PHEU) was synthesized by mixing hyperbranched polyether (PHEMO) with hexaethylene diisocyanate (HDD in the electrolyte. The effects of the concentration of lithium salt, the adding amount of electrolyte and the testing temperature on ionic conductivities of the polymer electrolytes were investigated via AC impedance technique. It shows that the as-prepared polymer electrolyte can achieve an ionic conductivity of 0.612 × 10^-3S/cm at room temperature. Cyclic voltammogram indicates that the polymer electrolyte has good electrochemical stability in the working voltage ranging from 2 to 4.5V. Therefore, it is suitable for application in lithium-ion battery.
