Gassing in sealed alkaline cells is prevented by making the negative electrode more porous than the positive electrode thus increasing the chemical activity of the negative electrode. The ratio of the porosity of the positive electrode to the porosity of the negative electrode is 0.8 or less. The negative electrode may be made of a finer grained material than the positive electrode, or the electrodes may be subjected to different pressures. |
