    Rechargeable batteries are the essential components for various devices in modern society, such as smartphones, tablets, and electric vehicles. The aim of this research is the fabrication of novel energy storage devices using "hydride ion" ― the anion of hydrogen. Because of its high reactivity, the chemical reactions in energy storage systems will be enhanced with hydride ions used as charge carriers and reactants. This contribution of hydride ion will enable to realize the high-performance energy storage device with large capacity, long lifetime, and safety.
