Original Abstract

The influence of addition of cobalt into the nickel oxide electrodes (NOE) on their stability and electrochemical performance was investigated. The article deals with the evaluation of the two options of NOE stabilization by cobalt addition. An electrode containing the cobalt in the whole volume of active material as well as an electrode which has active material covered by Co(OH)2 were prepared and measured. The different process of cobalt addition leads to the different electrode behavior. Whereas the first cobalt addition leads to the stable discharging capacities accompanied with negligible mass changes during cycling, the second one leads to the gradual increase of discharge electrode capacity. This capacity increase is accompanied with significant increase of electrode weight.
