摘要
为了降低贮氢合金中的钴含量,从而降低镍氢电池的价格,在贮氢合金M1Ni3 55Co0 75Al0 3Mn0 4的基础上,依次添加Cu、Cr、Zn、Fe元素,得到稀土基多元贮氢合金,并对其放电容量和循环稳定性进行了测试和分析。结果表明,适量的Cu、Cr、Zn、Fe替代Co,仍能使贮氢合金具有较高的放电容量和较好的循环稳定性。
<Abstrcat>In order to reduce the price of Ni-MH batteries by reducing the Co content in the alloys,Cu,Cr,Zn and Fe were added in turn into the alloy of M1Ni3.55Co0.75Al0.3Mn0.4 and multi-alloying RE based alloys were obtained.The results show that with Co being substituted by suitable amounts of Cu,Cr,Zn and Fe,the low Co hydrogen storing alloys can have high discharge capacity and good cycling stability.
