Metallic and complex hydride-based electrochemical storage of energy

Abstract The development of efficient storage systems is one the keys to success energy transition. There are many ways store energy, but among them, electrochemical particularly valuable because it can electrons produced by renewable energies with a very good efficiency. However, solutions currently available on market remain unsuitable in terms capacity, recharging kinetics, durability, and cost. Technological breakthroughs therefore expected meet growing need for storage. Within framework Hydrogen Technology Collaboration Program—H 2 TCP Task-40, IEA’s expert researchers have developed innovative materials based hydrides (metallic or complex) offering new field solid electrolytes anodes alkaline ionic batteries. This review presents state art research this field, from most fundamental aspects applications battery prototypes.
