Abstract

The present work presents results of a study of gel polymer electrolytes based on polyvinyl alcohol, propylene glycol and LiTFSI salt. Using methods of IR spectroscopy, differential scanning calorimetry, synchronous thermal analysis and impedance spectroscopy, the influence of composition on the chemical structure, thermal properties, and ionic conductivity of the materials was examined. The increase in the LiTFSI content was found to lead to a significant increase in electrical conductivity – up to 25,96·10–2 mS/cm at 343 K. Produced electrolytes demonstrate  high thermal stability and conductivity, which make them promising materials for application in solid-state power sources.
