(Source: Tokyo Institute of Technology) Japanese scientists demonstrate the first electrochemical reaction based on hydride ions in an oxide-based solid-state cell for potential next-generation batteries. Ionic transport has been studied extensively over the years for energy devices such as fuel cells and batteries using Li, H, Ag, Cu, F, and O. Yet as Genki Kobayashi and Ryoji Kanno point out in a recent report, hydride ions (H) may be particularly useful for high-energy-density storage and conversion devices. Using an oxyhydride solid state cell they have now demonstrated pure H conduction in an oxide for the first time. Metal hydrides tend to have an inflexible lattice, which makes H...
