Alkaline Storage Batteries: Factors Affecting the Hydrogen Evolution of Nickel-Iron Batteries While Standing Charge
Abstract
The rate at which hydrogen is given off after a charge to a negative plate is ended consists of three additive parts: (a) evolution of hydrogen which had been dissolved in the active iron during charge-time, one hour; (b) evolution of hydrogen corresponding to the decline of negative potential to the stationary potential-time, about 15 minutes; (c) hydrogen evolution at an essentially constant negative plate potential. When oxygen is absent, this rate is proportional to the area of the iron surface which is not covered with corrosion product. Mathematical analysis of the data indicates that the latter consists of a constant number of growing hemispheres.
