Abstract

The technical level of the batteries is still the bottleneck constraining the development of the whole electric vehicle industry. While the high-rate discharge of the hydrogen storage alloys is the main factors affecting the performance of Ni/MH batteries, so the development of high-power hydrogen storage alloys is the hot spots at present. The effect of Mn, Zr and La content on the electrochemical properties of AB_5.2-type Zr involved high-power hydrogen storage alloys was studied. The result showed that the Zr content should not be higher than 0.01, La/Mm should not be higher than 70%, and Mn content should be 0.4~0.6 depending on the value of La/Mm. The composition of the alloys was optimized and the alloy MmNi_3.89Co_0.4Mn_0.6Al_0.3 Zr_0.01 with good high rate discharge performance was developed.
