Recently, a research team headed by Professor Chen Ping from the Dalian Institute of Chemical Physics at the Chinese Academy of Sciences has achieved a groundbreaking feat: they've developed the world's inaugural gas-solid hydride ion prototype battery, also known as the "gas-solid battery." This innovative battery utilizes hydrogen gas and metals as its electrodes. Employing a "co-storage of hydrogen and electricity" approach, it enables simultaneous hydrogen charging during discharging and electric charging during hydrogen release. This marks a significant step forward in verifying efficient hydrogen storage methods under normal temperature and pressure conditions.

Hydride ions, recognized as a pivotal charge carrier for the forthcoming generation of all-solid-state batteries, are inherently unstable under natural circumstances. Nevertheless, after years of dedicated research, the team has successfully surmounted technical hurdles, including the stable conduction of hydride ions and the construction of all-solid-state batteries. Experimental data reveals that the battery's energy utilization efficiency soars to an impressive 93.9%, surpassing traditional thermal hydrogen storage by one-third. Moreover, it demonstrates stable operation across a broad temperature spectrum.

The team further demonstrated the battery's practicality by stacking battery cells to illuminate an LED bulb. This pioneering accomplishment obviates the necessity for extreme conditions, such as high pressure or deep cooling, which are typically required for traditional hydrogen storage methods. It paves the way for a novel technological approach to harnessing hydrogen energy.
