摘要:
The present invention provides a hydrogen absorbing alloy compact for use as the negative electrode of an alkaline rechargeable battery which is made without the aid of a current-collecting support, contains a binder dispersed in the interstices formed by mutual contact of hydrogen absorbing alloy particles and on the alloy surfaces, and has a bulk density of 3.5 to 6.0 g/cm3. The present invention also provides a compact electrode which is made by forming a porous hydrogen absorbing alloy compact containing neither current-collecting support nor binder, impregnating the compact with an aqueous solution (or solvent solution) of a binder, and then drying the compact to remove the water (or solvent) alone, so that the strength of the compact is increased and good electrical contact between alloy particles is established.

The object is to provide a hydrogen absorbing alloy suitable for the negative electrode of a Ni-hydrogen storage battery which is effective at low temperatures. The object can be attained by a LaNi.sub.5 type hydrogen absorbing alloy, wherein the content of Mg in the hydrogen absorbing alloy is 50 to 500 ppm, and it is represented by a general formula RNi.sub.a Co.sub.b Al.sub.c M.sub.d, wherein R comprises not less than 77 wt % La and 23 wt % or less of one or more metals other than La, Ni, Co, Al and M, M comprises at least one kind of metals selected from the group consisting of Fe, Cr, Cu and Mn, and a to d denote a positive number within a predetermined range. In addition, it is important to contain a small amount of Ti, Pb, oxygen, carbon and/or sulfur in said alloy.
