Electrodeposition of Metal from Polymer Electrolytes
Dočkal, M. ; Sedlaříková, M. ; Vondrák, Jiří
Theoretic part of this work contains a survey of the fundamentals of electrode processes with emphasis on galvanic metal deposition. The experiments with cadmiumelectrodeposition from liquid cadmium perchlorate solution in propylene carbonate, and from cadmium containing PMMA based gels are described in experimental part. The morphology of deposited metallic cadmium on copper was observed by scanning electron microscope. Dendritic growth and of the substrate and fine deposit organic compounds containing film was formed from liquid electrolyte, while corrosion appeared in contact with the gel.

Lithium ion batteries
Sedlaříková, M. ; Vondrák, Jiří ; Nečesal, P. ; Rozsívalová, Z.
Lithium ion batteries are the most promising accumulators from the viewpoint of specific energy. Their both electrodes are of intercalation type. Thus, their charge-discharge process is not accompanied by any change of electrolyte. Graphite is used as the material of negative electrodes while the positive electrodes are made from transition metal oxides such as manganese MnO2-x.
