Studies on Gel Electrolyte Based on Nitrile-Butadiene Copolymers

Abstract

This study is concerned with the preparation of a hybrid electrolyte, suitable for solid-polymer batteries. Based on the study of ionic conductivity in the presence of LiBF4 of a number of nitrile-butadiene copolymers (NBR), hydrogenated NBR (HNBR) was selected as the host polymer. DC conductivity studies with three different lithium salts in different plasticizers showed the highest conductivity for LiBF4. Conductivity of LiBF4 in different plasticizers decreases in the order DMF > DMAC > Gamma butyrolactone > NMP > PC=gamma- valerolactone > glymes. NMP was chosen as the plasticizer for hybrid films based on its moderate conductivity, low vapor pressure, and low freezing point. Polymer electrolytes, Gel electrolytes, Ionic conductivity.
