研究了不同热处理时间对MLNi3.8Co0.75Mn0.4Al0.2储氢合金电化学性能的影响。结果表明,经过不同时间热处理的储氢合金电极高倍率放电性及其放电容量均得到提高,其中经过6 h热处理后的合金电极在900mA/g和1200 mA/g的电流密度下的HRD最高,而原始合金电极在同样的放电条件下却不能放电。
The effect of different heat treatment time on the electrochemical performance of MLNi3.8Co0.75Mn0.4Al0.2 hydrogen storage alloy was studied. The results show that the high rate discharge and the discharge capacity of the hydrogen storage alloy after heat treatment for different time are improved. The HRD of the alloy electrode after 6 h heat treatment is the highest at the current densities of 900 mA / g and 1200 mA / g, The original alloy electrode in the same discharge conditions but can not discharge.
