As per the article, these Nickel Hydrogen batteries are very different to NiMH

> Nickel-hydrogen batteries look and work unlike any other battery. They consist of a stack of electrodes inside a pressurized gas tank. The cathode is nickel hydroxide while the anode is hydrogen. When the battery is charging, a catalytic reaction generates hydrogen gas. During discharge, the hydrogen oxidizes and converts back to water.

Sorry, yes. I was, however, describing my understanding of Nickel Hydrogen batteries' relationship with the square-cube law. Not NiMH.
