Stephenson, R F

An improved process for the electrolytic deposition of active material is described. The material may be in the form of a suitable metal hydroxide in a porous sintered nickel plaque, which in turn may be utilized to form the positive and/or negative electrodes of a nickel--cadmium battery. The process is characterized by the use of an organic acid such as formic acid as the buffering or support agent which effectively stabilizes the pH of the impregnating solution at an optimized value, while at the same time it avoids generating any particulate byproduct which would otherwise contaminate the solution; a virtually unlimited service life thereby results. Other advantages to the use of formic acid as the buffering material are disclosed as well.
