Effect of the distribution of the plasticizer in the polymer matrix on the conductivity of a gel polymer electrolyte based on the F-42L fluoropolymer

摘要

Transport processes in gel polymer electrolytes (GPEs) based on the F-42L fluoropolymer and 1 M LiClO4 in sulfolane were studied. Correlations between the GPE conductivity and both the polymer matrix structure and the properties of the electrolyte solution were revealed. In the polymer matrix, the electrolyte solution fills both its polymer globules and the interstitial space. The GPE conductivity is determined by the content of the electrolyte solution in the interstitial space.
