Seven-segment display unit
Vondrák, Jiří ; Velická, Jana ; Klápště, Břetislav ; Reiter, Jakub
The development of a seven segment numerical display unitusing WO3 and V2O5 electrodes on I.T:O: glasses, and gel polymerelectrolyte is described.
Synthesis and electrochemical study of polymer-electrolyte for high energetic density accumulator
Kerouani, N. ; Vondrák, Jiří
Polymer aprotic elektrolytes containing polyisobutyleneand polyethylene oxide and sodium or lithium salts wereprepared. Their conduction is of the order 10-4 S.cm-1at r.t. and both chemical and thermal stabilitysufficient.
Gel Polymer Electrolytes Based on PMMA
Vondrák, Jiří ; Klápště, Břetislav ; Velická, Jana ; Reiter, Jakub
Polymer gel electrolytes based on polymethylmethacrylateand aprotic solutions of metallic salts were prepared.Their electric conductivity decreased in the series ofsalts Mg>Li.>Zn>Na. The lower mobility of smaller ionsis explained by their stronger interaction with polymernetwork present in the gel.
Advanced Batteries and Accumulators Part I
Vondrák, Jiří ; Sedlaříková, M.
International conference on modern electrochemical powersources, their components and materials, and relatedapplications of elektrochemistry.
Advanced Batteries and Accumulators Part II
Vondrák, Jiří ; Sedlaříková, M.
The book of contributions of the section of ABA-1conference. This section was oriented on alkalineaccumulators and their development, and on thequestions of local nature connected to the industry.
Electrochemical Corrosion of Adhesive Joints
Vondrák, Jiří
The mechanism of corrosion, observed on adhesivejoints of steel to plastic, was explained by thesorption of hydrogen by steel and subsequentcreation of mechanical stresses.
