Cycling stability of La-Mg-Ni-Co type hydride electrode with Al SUN Xian-zhong(孙现众), PAN Hong-ge(潘洪革), GAO Ming-xia(高明霞), LI Rui(李 锐), LIN Yan(林 燕), MA Shuai(马 帅... stability of the La-Mg-Ni-Co based hydrogen storage alloy electrode was systematically investigated. The results show that the cell volume expansion upon hydrogenation is obviously decreased after......
. The alloy powder was immersed in a 6mol/L KOH solution at 70℃ for 18h. The negative electrode of Ni/MH battery was formed by mixing the alloy powder with a small amount of nickel and 3%(mass fraction... on metal alloy particles of negative electrode penetrating through the battery case. Table 2 shows the elements distribution on the surface of negative electrode(EDAX). It seems that ultrasonic can......
