| description | The invention relates to a low-cobalt iron-containing AB5 type hydrogen storage alloy and a preparation method thereof.The low-cobalt iron-containing AB5 type hydrogen storage alloy is of a CaCu5 type single-phase structure, the general formula of the low-cobalt iron-containing AB5 type hydrogen storage alloy is La (1-x-y-z) CexYyZrzNiaCobMnc AldFe, and the low-cobalt iron-containing AB5 type hydrogen storage alloy is prepared from raw materials through induction melting and melt-spinning. The AB5 type hydrogen storage alloy obtained by comprehensively regulating and controlling the alloy element composition and the preparation process can stably discharge at a low temperature and a high rate, is low in raw material cost, has relatively high capacity and relatively long cycle life, can realize low cost, high capacity and stable cycle, and is suitable for industrial production. And the material has excellent market application potential in the fields of power type nickel-metal hydride batteries, standby power |
