    摘要:

    系統(tǒng)地研究了粉末粒度對(duì)貯氫合金Ｍｌ（ＮｉＣｏＭｎＴｉ）５電化學(xué)性能的影響。結(jié)果表明，在２００μｍ－〈３８．５μｍ的粒度范圍內(nèi)，合金粉超細(xì)，其放電容量就越高，高倍率放電性能就越好，循環(huán)穩(wěn)定性就越佳；將兩種不同粒度的合金粉混合使用時(shí)，兩種合金粉的粒徑相差較大，其放電容量越高，且當(dāng)粗細(xì)粉質(zhì)量比為７：３時(shí)，放電容量達(dá)到最高。

    Abstract:

    The effects of particle size on the electrochemical properties of the Ml(NiCoMnTi)5 hydrogen storage alloy have been systematically investigated. The results show that the smaller the particle size, the higher the discharge capacity and the better the high -rate-dischargeability and the cycling stability. If two types of powder with different particle sizes are mixed, the smaller the particle size ratio (the average particle size of small component to that of the large one), the higher the discharge capacity. At a mixing weight ratio (the weight of large component to that of the small one) of 7: 3, the highest discharge capacity is obtained.
