This paper deals with preparation of gel electrolyte based on copolymers. Copolymer is a new material, which consists of two different monomers. The main goal of this work was to find a new gel electrolyte with conductivity more than 5 mS/cm with a good electrical stability and good mechanical properties. Impedance spectroscopy and linear voltammetry were used for measurement electrical conductivity and potential window.

Variety of methacrylates was used as the component for preparation of gel polymer electrolytes for lithium batteries. The monomers containing short aliphatic chain were indicated as suitable and their conductivity was in the range from 1 to 6 mS/cm. The good mechanical properties of them seemed important.

Flame retardants can solve a problem with flammability of electronic devices. This article deals with preparation of gel polymer electrolytes, which are used in lithium batteries, modified by flame retardants. Gel polymer electrolytes with selected additives, were prepared by different methods. Electrochemical and thermal properties were measured of all prepared gel polymer electrolytes.

This paper deals with a method of preparation of gel polymer electrolytes modified by flame retardants. The method is characterized that as a solvent, one type of flame retardant is used here. Other components from basic chemical composition of a gel electrolyte didn’t change. The work is focused on measuring electrochemical and electrical properties of gel polymer electrolyte. Electrochemical properties were measured by linear voltammetry and impedance spectroscopy.

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-based polymer). In this paper, I present fundamental characteristics of gel polymer electrolytes modified nanoparticles or copolymers and preparation of these gel polymer materials with nanoparticles or copolymers polymerized in electric and magnetic fields.
