	Přídavky manganu a niklu do elektrodových materiálů lithno-iontových baterií Jirák, T. ; Vondrák, Jiří ; Sedlaříková, M. ; Hejátková, E. The properties of electrode material based on LiCoO2 were modified by substitution of cobalt by Ni and/or Mn compounds. Specific energy of new material was lower, but their lifetime (number of cycles) was improved. Detailed record
	MnO2 studovaný metodou EQCM Špičák, P. ; Svoboda, V. ; Sedlaříková, M. ; Vondrák, Jiří ; Kazelle, J. Mass changes of electrodes containing MnO2 during charging and discharging processes were studied using QCMB techniques. The process is accompanied by reversible uptake of water and insertion of H3O+ insted of H+ should be expected. Detailed record
	Nanotrubice jako příměs do kladné elektrody Li-iontové baterie Sysel, M. ; Makovička, J. ; Sedlaříková, M. ; Vondrák, Jiří Active mass for positive electrode of Li-ion batteries should be improved by carbon particles for enhancement of electrical conductivity. Carbon nanotubes were tested for this purpose. Detailed record
	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. Detailed record
	Application of NMR techniques for investigation of ionic mobilities in gel electrolytes Nováček, T. ; Vondrák, Jiří ; Sedlaříková, M. The mobility of Li and Na ions was observed both by specific conductivity and NMR line widening in Li and Na gels. Detailed record
	Electrochromic electrodes investigated by QCB Špičák, P. ; Svoboda, V. ; Sedlaříková, M. ; Vondrák, Jiří ; Kazelle, J. The application of crystal quartz ballance for the investifation of intercalation electrodes. Detailed record
	Dvojvrstva na uhlíku v aprotických elektrolytech Vondrák, Jiří ; Sedlaříková, M. ; Velická, Jana ; Kocian, Martin ; Špachman, V. ; Klápště, Břetislav As carbonaceous materials we started with glassy carbon electrodes and continued to use variety pf carbon black powders, carbon nanotubes and chemically modified graphite in powderized form. Detailed record
	Příprava a vlastnosti elektrod V2O5 pro elektrochromní součástky Macalík, M. ; Matěj, A. ; Sedlaříková, M. ; Vondrák, Jiří The preparation of SnO2 based layers by spray method seems interesting for the technology as no vacuum is necessary for it. Vanadium oxide films were dip-coated on FTO layers. Detailed record
	Redukce kyslíku v elektrolytu obsahujícím hydroxid a borohydrid sodný Chatenet, M. ; Micoud, F. ; Roche, I. ; Chainet, E. ; Vondrák, Jiří The Principle of double layer on carbon electrode has been used for the design of new components, called electrochemical supercapatitors. Detailed record
	Elektrody pro elektrochromní zařízení studované pomocí EQCM Špičák, P. ; Svoboda, V. ; Sedlaříková, M. ; Vondrák, Jiří ; Kazelle, J. The crystal surface with the layer is exposed to the electrolyte in a three-electrode systems, usuallydriven by potentiostat. This frequency change is used for detection ofchemical changes of the electrode surface.This system is very sensitive. Detailed record
