Within the framework of the Hydrogen Technology Collaboration Program—H2TCP Task-40, IEA’s worldwide expert researchers have developed innovative materials based on hydrides (metallic or complex) offering new solutions in the field of solid electrolytes and anodes for alkaline and ionic batteries. This review article, coordinated by Michel Latroche, presents the state of the art of research in this field, from the most fundamental aspects to the applications in battery prototypes.
