| Resumo: | This paper describes electrochemical and spectroscopic studies on the utilization of cerium atoms as additives for nickel hydroxide electrodes. Thin films were galvanostatically grown with different amounts of cerium and mixed electrodes were studied by electrochemical measurements and the spectroscopic technique. The electrochromic behavior was investigated by "in situ" experiments , while the amount of species was determined by ICP-OES. The addition of cerium to nickel hydroxide electrodes increases durability, due to modifications in the structural properties, as seen by Raman spectras. |
