Gel polymer electrolytes with high fire safety
 Musil, Michal ; Zatloukal, Miroslav (referee) ; Sedlaříková, Marie (advisor)
This work deals with preparation of PMMA based gel polymer electrolytes with high fire safety and high ionic conductivity. In the theoretical part of the work GPEs for Li – ion accumulators, fire safety tests, fire retardants are mentioned. Preparation of GPEs, electrical and other properties are described in the experimental part. Furthermore, new possible methods of gel preparation are discussed.

Electrochemistry in the Medium of PMMA Gel Electrolytes
 Reiter, Jakub ; Vondrák, Jiří ; Sedlaříková, M. ; Velická, Jana ; Nečesal, P.
Polymer gel electrolytes are used in the electrochemistry of lithium batteries and electrochromic devices. Their investigation started in our department in 1997, when first results were published on the International Seminar on Inclusion Compounds. Investigation of electric conductivity showed, that the specific conductivity of a 0.25 M LiBF4 solution was not lowered by an addition of solid PMMA polymer more than by 40-50%. We have developed a new method preparation of gel polymer electrolyte: after a mixung of anhydrous perchlorate solution in propylencarbonate (lithium, sodium, cadmium and other sals) with monomeric and oligomeric metylmetacrylate we hawe obtained an elastic and homogenous polymer with good optical properties.
