We prepared a polymer electrolyte by blending PEGDA with PVdF and PMMA. PVdF was added to improve mechanical properties and PMMA was to impede the outflow of organic solvent by increasing an affinity for it. To study electrochemical properties of the blend polymer electrolyte, we investigated ionic conductivity, electrochemical stability window and battery performance as a function of blend ratio and amount of initiator. Also we studied the mechanical properties of the blend polymer electrolyte.
