Ionic Association in CH₃-(CH₂-CF₂) _n -CH₃(PVDF)-Li⁺-(CF₃SO₂)₂N^- for n = 1, 4: A Computational Approach.

ABSTRACT: The ionic conductivity of solid polymer electrolytes is governed by the ionic association caused by the polymer···Li⁺ and the anion···Li⁺ interactions. We performed the density functional calculation to analyze the molecular interactions in the CH₃-(CH₂-CF₂) _n -CH₃-Li⁺-(CF₃SO₂)₂N^- for n = 1,4 systems. The gauche conformation is predicted in the lowest energy conformer of pure polymer except for n = 1. The lithium coordination number with the polymer is changed from 3 to 2 in the presence of anion for n = 2, 4 systems. The consequences of the Li⁺ ion and Li⁺-(CF₃SO₂)₂N^-
