In this study, it has been experimentally proven that the pocket electrodes of the Ni-Fe batteries in the process of their operation absorb hydrogen in large quantities. There is no hydrogen inside the electrodes of new batteries, but after 6 years of service life the electrodes reach their maximum hydrogen capacity. The active mass capacity of an oxide-nickel electrode as a hydrogen absorber was quantified as 22 wt% and 444 kg.m(-3). These values exceed 3 times the earlier obtained results (using traditional methods) for hydrogen absorption by carbon nanostructures or any other carbon materials. (C) The Author(s) 2017.
