Abstract

The electrochemical properties of the Ti_2.8C_0.2Ni₂, Ti₃Ni_1.8C_0.2 and Ti₃Ni₂ alloys prepared by powder sintering were studied. The results show that Ti_2.8C_0.2Ni₂ and Ti₃Ni_1.8C_0.2alloys possess lower corrosion rate and better anti-pulverization in alkaline electrolyte. Therefore, the cycle life of Ti_2.8C_0.2Ni₂ and Ti₃Ni_1.8C_0.2 alloys is significantly improved compared with that of Ti₃Ni₂. The capacity retention of them increases to 66.4% and 63% respectively, much higher than that of the original Ti₃Ni₂ alloys (53.4%). In addition, Ti₃Ni_1.8C_0.2 alloy has better maximum discharge capacity C_max of 316.8 mAh/g than the original Ti₃Ni₂ alloy (305.3 mAh/g). All the three alloys with excellent property of HRD, can still remain above 62% of HRD at discharge current density of 1100 mA/g. After C substitution, the HRD of alloys are further improved, especially that of Ti₃Ni_1.8C_0.2 alloy.
