摘要

PCT No. PCT/JP96/02761 Sec. 371 Date May 22, 1997 Sec. 102(e) Date May 22, 1997 PCT Filed Sep. 25, 1996 PCT Pub. No. WO97/12408 PCT Pub. Date Apr. 3, 1997This invention relates to a hydrogen absorbing electrode, in which a rare earth element having a basicity weaker than that of La is mixed to a hydrogen absorbing alloy or contained in it for serving as a component element. The invention relates to a nickel electrode, in which a rare earth element is mixed to a nickel hydroxide or contained in it as a solid solution. The invention further relates to an alkaline storage battery, in which a rare earth element is coated on a surface of a nickel electrode or a surface of a separator.
