摘要
利用正交实验研究了贮氢合金的组成及各元素的含量对高倍率放电性能的影响,得出最佳配比为La0 71Ce0 1Pr0 09Nd0 1Ni4 4Co0 2Mn0 2Al0 2。随着La含量在一定范围内的增加或者Co和Al含量的减少,合金高倍率放电能力会得到改善,Mn含量在一定范围内变化对高倍率放电性能的影响不大。研究了粒度对高倍率放电性能的影响,粒度为200～300目最佳。
The effect of the composition of hydrogen storage alloy and the content of its elements on high-rate discharge ability were studied by orthogonal experiment.The optimized composition was La_(0.71)Ce_(0.1)Pr_(0.09)Nd_(0.1)Ni_(4.4)Co_(0.2)Mn_(0.2)Al_(0.2).The high-rate discharge ability of alloy electrodes were improved with the increase of La in some area and the decrease of Co and Al.The change of Mn content had less effect on it.The effect of graininess on high-rate discharge ability was studied, the proper granularity was in 200～300 mesh.
