Ruthenium and its ability to absorb hydrogen somehow was made into a battery prototype by some researchers at the University of Tokyo. It was demonstrated to hold a charge better than lithium ion batteries with nearly 96% retention of the incoming charge over a period they claimed reached months. The size of the prototype was equal to that of a standard laptop battery, yet in a small battery bank series powered an electric car motor at full speed for hours. I thought this would have been world news by now, yet there is silence. Does anyone have more info? Can somebody out there get some more info out of Tokyo if you have access to this technology? Why is it being kept "under wraps"? It did not seem to overheat as the lithium ion storage method does. What would be difficult about producing more than a prototype of a ruthenium based battery?
