The electrochemical properties of new type Ti 3Ni 2 hydrogen storage electrode have been studied in detail. It is shown that the largest discharge capacity of Ti 3Ni 2 electrode reaches 384 5 mAh/g at 353K and 145 5 mAh/g at 278 K (corresponding to Ti 3Ni 2H 3 7 and Ti 3Ni 2H 1 47 hydride respectively). At high temperature (353K) two plateaus of discharge curve appear, but at low temperature only one plateau. Compared with Ml (NiCoA1Mn) 5 electrode, the dynamics of Ti 3Ni 2 electrode is poor. The discharge capacity, dynamics and charge retentivity of Ti 3Ni 2 electrode are improved greatly at high temperature.
