Abstract

784,851. Batteries. ACCUMULATORENFABRIK AKT.-GES. Nov. 28, 1952 [Dec. 1, 1951], No. 30287/52. Class 53. To prevent gassing in a sealed alkaline accumulator if the polarity should become reversed when a number of such cells having positive and negative electrodes of the same capacity are joined in series, the positive electrode contains a quantity of negative active material in addition to the normal positive material, and the negative electrode contains some positive active material in addition to the negative material. Only one of the electrodes has the additional active material if the other electrode is large and is provided with an excess of the normal active material. The additional active material may be mixed with the normal active material or it may be contained in separate pockets or tubes forming a part of the electrode. In an example the positive electrode comprises nickel hydroxide, nickel flakes and graphite with an addition of cadmium oxide or hydroxide. The negative electrode may consist of cadmium or iron with an addition of nickel hydroxide, cobalt hydroxide or copper powder. Specification 433,809 is referred to.
