Electrochemical Properties Of Gel Polymer Electrolytes Modified Flame Retardants
Veselkova, Iuliia
This paper deals with preparation of gel polymer electrolytes modified by flame retardants based on methyl methacrylate. The aim of this work was to investigate the effect of thermal polymerization method on electrochemical properties such as ionic conductivity and potential window of gel polymer electrolytes. For measuring electrochemical properties, impedance spectroscopic techniques and linear voltammetry were used. Results indicate the dependence of ionic conductivity on the amount of flame retardant.
