Centre for Hydride Energy Chemistry

Of hydrogen's three valence states - positive (+1), neutral (0), and negative (-1), the hydride ion (H-) is the most energetic and reactive, making it the central focus of our center. We are dedicated to uncovering the distinctive properties of hydride materials harnessing them to drive advances in hydrogen storage, ammonia synthesis, and hydride ion conduction.

Our group has pioneered a hydride ion battery, representing a breakthrough in clean energy storage. Using a novel core-shell electrolyte, the team achieved room-temperature operation, verified by powering an LED. This leap from concept to reality opens new pathways for large-scale energy storage and mobile power, bolstering China's green energy future. (Nature 2025, DOI: 10.1038/s41586-025-09561-3)

Launched Jan 10, 2025, a 150 t/y MgH₂ pilot plant is now in trials. This joint initiative uses a proprietary one-pot method to produce this key hydrogen storage material, advancing solid-state hydrogen storage for renewable energy integration and the ‘dual carbon’ goal.

Our group has pioneered the first room-temperature hydride ion battery, a breakthrough in clean energy storage. By engineering a lanthanum hydride material with a nano-grained, defective structure, the team suppressed electron flow by five orders of magnitude while enabling rapid hydride ion movement. This enables a pure ion conductor for a solid-state battery operating from -40°C to 80°C, paving the way for a new class of all-solid-state energy storage devices.
