Polymer electrolytes based on acrylonitrile-butadiene-styrene copolymer

One of the approaches to improving the ionic conductivity and the mechanica l strength of a solid polymer electrolyte is to use polymers in modified fo rms, such as polymer blends, copolymers and cross-linked polymers. In this study, a new polymer electrolyte based on the acrylonitrile-butadiene-styre ne (ABS) copolymer has been prepared. The ionic conductivity, electrochemic al stability and interfacial characteristics of the polymer electrolyte in contact with a lithium electrode have been investigated. The temperature de pendence of the conductivity below 20 degrees C can be described by the Arr henius equation, and above 20 degrees C by the VTF equation. Lithium passiv ation appeared to have taken place in the system. The conductivity and elec trochemical characteristics of the system are somewhat similar to those of PAN-based polymer electrolytes.
