In this study, it has been experimentally proven that the electrodes of the Ni-Cd batteries in the process of their operation absorb hydrogen in large quantities. There is no hydrogen inside the electrodes of new batteries, but after five years of service life the electrodes reach their maximum hydrogen capacity. The capacity of an oxide-nickel electrode as a hydrogen absorber was quantified as 13.4 wt% and 400 kg m3. These values exceed twice the earlier data obtained for any reversible metal hydrides, obtained using traditional methods. © 2012 The Electrochemical Society. Source

A structural model is proposed for self-discharge in alkaline batteries. It was demonstrated that existing empirical equations for the self-discharge process are special cases of a general solution. Furthermore, the empirical equations do not contradict each other; rather, they supplement each other, since each is correct over a different time interval of self-discharge. © 2012 The Electrochemical Society.
