The present invention discloses negative electrodes for alkaline storage batteries and their methods of fabrication. The material for said negative electrode comprises of an additive that has at least one calcium compound selected from the following: tricalcium silicate, dicalcium silicate, and tricalcium aluminate. The concentration of said additive is between 1 wt % and 15 wt % of the material of said negative electrode. To fabricate said negative electrode, said additive is mixed with an active material for the negative electrode to form a paste, which is then dried. This method of fabrication is simple, convenient and low in cost. An alkaline battery using said material for its negative electrode has long cycle life and a large capacity.
