Original Abstract

Due to the low cost, long chemical and mechanical stability and reasonably high conductivity, the PMMA based electrolytes are suitable for various applications in the field of solid state electrochemical devices such as lithium batteries, electrochromic elements and solid-state sensors. As optional part inorganic and/or organic compounds can be used, which determines chemical and optical properties of the gel. They are freeze resistant to -25oC. The UV initiated polymerisation yields in gels with lower conductivity than the chemically polymerised materials. Further, smaller cations are less mobile than larger ones. Fc/Fc+ redox couple immobilised in the gel is a suitable redox system for description of electrochemical changes during the polymerisation. The diffusion coefficients for ferrocene and ferricinium cation were estimated. The properties of a glassy carbon electrode in contact of the gels are important for the usage of gels in electrochemical supercapacitors. The double layer capacity is quite within the expected values.
