Description
Summary:Effects of thermal history and storage time on electrochemical properties, morphology and stability of the polymer composite electrolytes of poly(ethylene oxide) with LiClO 4 and LiCF 3SO 3 have been studied. Complex ac impedance, dc polarization, thermogravimetric analysis, and differential scanning calorimetry have been used. These electrolytes were prepared as thin films by solution casting and had various thermal histories. It is considered that the different effects of thermal history result from different recrystallization kinetics of composite electrolytes.
