Abstract

MoO3 was added to the zinc electrode of Zn/KOH/NiOOH cells. The combination of anodic polarization curve, constant current charge–discharge, and impedance spectra was used to investigate the effects of adding MoO3 on the electrochemical performance of zinc anode. The cell with MoO3 added in zinc anode reached 360 cycles before its capacity fell below 90 % of the initial capacity, while the cell without MoO3 failed after 180 cycles. Based on the scanning electron microscopy observation, the significant improvement of cycle stability can be attributed to the addition of MoO3, which helps zinc electrode to stay in a loose and porous structure, such texture is definitely in favor of the diffusion of OH− ions, facilitating the utilization of active material. But for standard electrode without MoO3, zinc anode is easy to passivate owing to the formation of dense ZnO film on zinc electrode surface. This compact film restricts OH− ion diffusion and decreases active area of zinc electrode. Therefore, MoO3-added electrode can effectively improve the cycle performance of the Ni–Zn battery.
