Abstract

The compound powders of VB2 with 25 wt% and 50 wt% Ni were mixed uniformly using a planetary ball miller, respectively. The discharge capacity of VB2/air battery with VB2-Ni as anode in KOH electrolyte was investigated at room temperature and ambient pressure. Meanwhile, the microstructure of VB2-Ni anode before and after discharge were analyzed by scanning electron microscope (SEM).The results indicate that the sintered anode material of VB2 with 25 wt% Ni has the highest discharge capacity. Moreover, the discharge capacity of VB2/air battery reached 7574 mAh with sintered VB2-Ni25wt% anode, which was much higher than that with unsintered VB2-Ni25wt% anode. However, the discharge capacity of VB2/air battery with sintered VB2-Ni50wt% anode was much lower than that with unsintered VB2-Ni50wt% anode. The VB2-Ni25wt% anode sintered at 1050 oC for 30 min is an effective way to improve the discharge capacity of VB2/air battery.
