The influence of substitution Co for Ni on the phase structure and electrochemical properties of La4MgNi19 phase composition alloys have been investigated systematically.The structure analyses show that the alloys are mainly composed of multiphase,such as CaCu5 phase ,Pr5Co19 phase and Ce5Co19 phase.The electrochemical measurement showed that alloy electrodes could be activated in 2-3 cycles, with increasing of x value, the maximum discharge capacity gradually increased from 345.7 mA·h/g (x = 0.0) to 382.8 mA·h/g (x = 2.0), cyclic stability increased a little ,but high-rate dischargeability (HRD) decreased somewhat. It is found that the HRD was mainly controlled by the electrocatalytic activity on the alloy electrode surface,and the improvement of cyclic stability was due to the increase of CaCu5 phase and Ce5Co19 phase . CaCu5 phase increased with increasing Co content. Ce5Co19 phase has a small corrosion rate in the electrochemical cycle.
