2. Chinese scientists develop first superionic hydride ion conductor at ambient conditions

Chinese scientists have developed the first superionic hydride ion conductor at ambient conditions, according to the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences.

With strong reducibility and high redox potential, the hydride ion (H-) is a reactive hydrogen species and an energy carrier. Materials that conduct pure H- at ambient conditions will be enablers of advanced clean energy storage and electrochemical conversion technologies.
