Resumen:
In this paper, the study of nickel hydroxide porous electrodes containing differentconcentrations of cobalt as additive (2e10%), polytetrafluoroethylene (PTFE) as bindermaterial and prepared by chemical impregnation on nickel sintered substrate, are presented.The characterization of the different electrodes is performed using optical techniquessuch as scanning electron microscopy (SEM), energy dispersive X-ray analysis(EDAX) and electrochemical techniques as cyclic voltammetry, charge-discharge curvesand electrochemical impedance spectroscopy (EIS). The results indicate that the concentrationof 5% metallic Co improves the electrochemical behavior of the active material.
