【Abstract】 The influence of Co, Mn and Al as the replacement elements on the performance of Mm-Ni based hydrogen storage electrode alloys at different temperature and different discharging rate has been studied. It was showed that the replacement elements can stabilize the hydride formed by Mm-Ni based alloys and hydrogen, make the alloys have a wider range of temperature for discharging; but they are somewhat harmful to the dynamic characteristics of reaction between the alloys and hydrogen, reduce the discharging efficiency as temperature lowers, and make the performance deteriorate at high discharging rate.更多还原
