Abstract

In poly(vinylidene fluoride) (PVDF)-based electrolytes, residual solvents play a crucial role in determining the electrolyte performance. Herein, the influence of various residual solvents on electrolyte properties is investigated through atomistic modeling. It is found that fluorination and reduced molecular volume can facilitate fast ionic diffusion and enhanced cycling stability.
