摘 要: 從電化學角度研究了含錫貯氫合金的貯氫性能，并對金屬氫化物電極制作技術(shù)進行了探索。結(jié)果表明，用這種貯氫合金制成的電極容量達到340 mAh/g以上，而且容易活化。采用顆粒細小的鎳粉較粒徑較大的銅粉好，導(dǎo)電劑用量10％；采用混合粘結(jié)劑CMC和PTFE，CMC用量為0.4％，PTFE用量為10％。

Abstract:The characteristics of LaNi5-type Sn-containing hydrogen-storage alloy were studied electrochemically. The preparation technique of hydrogen-storage electrode was explored. The results showed that the discharge capacity of the electrodes, made up of this alloy with good initial capacity, is over 340mAh/g; as the conducting material, nickel powder with smaller size is better than copper powder with larger size, and its amount is 10%. The adhesive used in study was a mixture of 0.4%CMC and 10%PTFE.
Key words: metal hydride electrode Ni/MH battery hydrogen-storage alloy
