Aprotické gelové polymerní elektrolyty
Vondrák, Jiří ; Sedlaříková, M. ; Krejza, O.
The systematic research of gel polymer electrolytes started in the days of 1st and 2nd Lithium Battery Meetings in Italy. The idea was rather unique - to "thicken" an aprotic solution of lithium sall with an inert polymer.
Studium gelových elektrolytů na bázi PMMA a obsahujících ionty Na+ pomocí nukleární magnetické rezonance
Vognar, J. ; Macalík, M. ; Špičák, P. ; Vondrák, Jiří ; Novák, V. ; Krejza, O. ; Bartušek, Karel
Mixture of liquid MMA and PC displays significantly longer relaxation times T1 and T2 than clear solution of NaClO4 in PC. Possibly reason is that the presence of MMA release solvatation of ions Na+ by propylencarbonate.
Polymerní elektrolyty na bázi methakrylátů pro elektrochromní zařízení a lithno-iontové baterie
Krejza, O. ; Reiter, Jakub ; Vondrák, Jiří
Poly(ethyl methacrylate) and poly(2-ethoxyethylmethacrylate) polymer electrolytes with embedded aprotic solvents (carbonates) and lithium perchlorate and lithium bis(oxalato)borate were tested in electrochromic devices and lithium-ion batteries.
Pokroky ve výzkumu aprotických gelových elektrolytů v České republice
Vondrák, Jiří ; Sedlaříková, M. ; Krejza, O. ; Velická, Jana
The progress of research of gel polymer electrolytes based on polymethacrylates and propylene carbonate is described. The electric conductivity and selected electrochemical processes in them is the main research field.
Byly sestrojeny hybridní elektrochromní prvky s různými elektrolyty a studovány jeho optické a elektrochemické vlastnosti
Krejza, O. ; Reiter, Jakub
Hybride electrochromic devices were assembled with different electrolytes and their optical and electrochemical properties were studied.
Specific conductivity of PMMA based gel electrolytes containing cadmium, magnesium or lithium salts
Krejza, O. ; Nováček, T. ; Vondrák, Jiří ; Sedlaříková, M.
A subject of our research was checing and obtaing new pieces of knowlegdge about specific electric conductivity of PMMA based gel electrolytes.
Srovnání hybridních elektrochromních článků použitím sol-gel a polymerních elektrolytů s redoxním párem I3-/I-
Šurca-Vuk, A. ; Krejza, O. ; Ješe, R. ; Štangar, UL. ; Orel, B. ; Reiter, Jakub ; Vondrák, Jiří
The aim of this study is the comparsion of the hybrid electrochromic cells(HEC) incorporating sol-gel or polymeric I3-/I- redox electrolyte.
