Nickel-cadmium cell and method for precharging negative electrode of nickel-cadmium alkaline storage cell

Patent ·
OSTI ID:5163511
A method for precharging the negative electrode of a nickel-cadmium alkaline storage cell the electrodes of which are assembled in an at least partially discharged state is disclosed. 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 C/sub x/H/sub y/O/sub z/, 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. 2 tables.
