Resumen:
The effects of cobalt additive on the positive electrode surface of nickel alkaline batteriesare investigated. Electrode surface modifications by electroless cobalt deposits were madeat different immersion times. The performance of nickel hydroxide electrodes was studiedby optical techniques, such as scanning electron microscopy (SEM), energy dispersive X-rayanalysis (EDAX) and electrochemical methods as cyclic voltammetry, chargeedischargecurves and electrochemical impedance spectroscopy (EIS). According to these results,electroless cobalt deposits obtained with 5 min of immersion time in the electroless-bathexhibit a better electrode performance.
