Amelioration du procede d´impregnation electrochimique d´electrodes d´hydroxyde de nickel

Nickel hydroxide electrodes containing about 11g/dm² of hydroxide, with capacities of 3.6 to 3.8 Ah/dm² may be prepared at 353??K by electrochemical impregnation. The reproducibility of the results are obtained by reajusting the pH before each preparation. The control of each electrode is done during two cycles of charge and discharge following the manufacture by means of a potential relaxation method.
