Abstract

Polymer electrolytes are considered as the most commercially valuable solid electrolytes due to their flexibility and electrochemical stability. In this work, we prepared solid polymer electrolytes (SPEs) based on poly(ethylene oxide) (PEO) and a liner amorphous copolymer 2,4 -toluene diisocyante/polyethylene glycol (TDI/PEG). The optimal electrolyte PEO/TDI/PEG(PTP) with 20% TDI-PEG content presents a maximum conductivity of 0.17 mS cm-1 at 60
