This invention relates to an electrode composed of an active material. This electrode comprises a composition of a hydrogen storage alloy powder possessed of relatively high electrochemical capacity with a formula of MmNi5-x-y-z AxByCz and a hydrogen storage alloy powder possessed of catalytic activity with a formula of D2-uE1-vFuGv wherein Mm is the mischmetal, A=Co, Cr, V; B=Mn, Sn, Be; C=Al, Ca, Mg, Zr, Nb; D=Mg, Al; E=Cu, Zn; F=Ca, Be; G=Sn, Bi; 0.ltoreq.x.ltoreq.0.5, O.ltoreq.y.ltoreq.l.5, 0.ltoreq.z.ltoreq.0.5, 0.ltoreq.u.ltoreq.1, 0.ltoreq.v.ltoreq.0.5. The internal pressure of the alkali battery assembled with this electrode can be effectively lowered, the capacity and the cycle life of the sealed battery are improved, the activation period of the battery is shortened to 3-5 times, thus the crucial technical problem about industrial mass production of this kind of alkali batteries is surmounted.
