摘    要：从电化学角度研究了含锡贮氢合金的贮氢性能，并对金属氢化物电极制作技术进行了探索。结果表明，用这种贮氢合金制成的电极容量达到340 mAh/g以上，而且容易活化。采用颗粒细小的镍粉较粒径较大的铜粉好，导电剂用量10％；采用混合粘结剂CMC和PTFE，CMC用量为0.4％，PTFE用量为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.
