Studium rheologických a elektrolytických vlastností elektrolytů pro lithiové baterie na bázi dimethylformamidu a -gama –butyrolaktonu
Kerouani, N. ; Chelali, N. ; Vondrák, Jiří
The conductivity is an important characteristic of the electrolyte and it has to be the highest possible because it is of the prime importance for the Li-batteries improvement life. New electrolytes based on dimethylformamide and gamma-butyrolactone were studied.
Příprava dopovaných SnO2 tenkých vrstev ze SnCl2 a SnCl4
Maršík, P. ; Vondrák, Jiří ; Koten, S. ; Macalík, M.
Thin layer electrodes based on SnO2 were prepared by two methods (sputtering and spray deposition ) and their electrical and electrochemical properties compared.
