A method for precharging the negative electrode of a nickel-cadmium alkaline storage cell whose electrodes are assembled in an at least partially discharged state, wherein before the first charge of the cell, a calculated quantity of a material is introduced in the cell, such material being irreversibly oxidizable in an alkaline medium at a potential such that it is anodically oxidized before nickel hydroxide without evolving any gas, then the cell is charged in the normal way. The material preferably is an organic material of the general formula CxHyOz; most preferably where x=n, y=2n+2, and z=1, with n less than 4. This particular class of materials comprises the three saturated mono-alcohols: methanol, ethanol and propanol. |
