Polymer electrolytes based on acrylonitrile-butadiene-styrene copolymer

Abstract

One of the approaches to improving the ionic conductivity and the mechanical strength of a solid polymer electrolyte is to use polymers in modified forms, such as polymer blends, copolymers and cross-linked polymers. In this study, a new polymer electrolyte based on the acrylonitrile-butadiene-styrene (ABS) copolymer has been prepared. The ionic conductivity, electrochemical stability and interfacial characteristics of the polymer electrolyte in contact with a lithium electrode have been investigated. The temperature dependence of the conductivity below 20 °C can be described by the Arrhenius equation, and above 20 °C by the VTF equation. Lithium passivation appeared to have taken place in the system. The conductivity and electrochemical characteristics of the system are somewhat similar to those of PAN-based polymer electrolytes.
