Schematic diagram of the first room temperature all-solid-state hydride ion battery. Credit: DICP Scientists have built the first rechargeable hydride ion battery. Hydride ions (H⁻) have drawn interest as potential charge carriers for future electrochemical devices because of their extremely low mass and high redox potential. Yet, progress has been limited since no electrolyte has been able to provide the combination of rapid ion movement, thermal stability, and compatibility with electrodes t...
