Gel Polymer Electrolytes for Use in Lithium-ion Batteries

Abstract

Gel polymer electrolytes are perspective electrolytes for new types of Li-ion batteries today. The properties respectively advantages of these gels can be used also in other fields of electrochemistry. The gel polymer electrolyte is composed of a conductive component (liquid electrolyte) and the polymer component (methacrylate). In this paper I present fundamental characteristics of gel polymer electrolytes. This paper presents a principle of gel polymer electrolytes, fundamental measurement and their evaluation. I present the techniques of measurement and preparation of this gel polymer materials. Potentiostatic impedance, linear sweep voltammetry, cyclic voltammetry and galvanostatic charge/discharge techniques were used for characterization of the samples.
