Resumen:
The discharge process of nickel hydroxide electrodes obtained by electrodeposition isstudied by electrochemical impedance spectroscopy (EIS). The results are discussedaccording to a physicochemical model, taking into account the porous nature of theelectrode, the charge transfer process and the H transport in the active material. Theparameter identification procedure allows estimating of values related to the interfacialarea per unit volume, the solid and solution conductivities as well as diffusion and kineticconstants related to the discharge process.
