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
