An Oxygen Electrode Based on Nickel/Cobalt Spinel,

Abstract

It has been demonstrated that nickel/cobalt spinel, NiCo2O4, can be prepared simply and inexpensively by the thermal decomposition of cobalt nitrate on sintered nickel plaque. Electrodes suitable for use in metal/air batteries and fuel cells have been developed which will reduce oxygen from the air at room temperature and a current density of 50mA/sq cm for more than a year. A modification of this electrode will perform satisfactorily for more than 200 cycles of oxygen reduction/oxygen evolution at 50mA/sq cm. (Author)
