Our research group developed the first gas-solid hydride ion battery that enables efficient hydrogen storage under ambient temperature and pressure, eliminating the need for extreme condition such as high pressure (700 atm) or cryogenic temperatures (-253°C). This battery utilises hydrogen gas as the positive electrode and magnesium metal as the negative electrode. During discharge, hydrogen is...
Efficient hydrogen storage remains one of the most critical challenges limiting the widespread adoption of hydrogen energy technologies. Conventional hydrogen storage methods typically rely on extreme conditions, such as high-pressure compression (up to 700 atm) or cryogenic liquefaction (−253 °C), resulting in high energy consumption, safety concerns, and increased system complexity. Developi...

Recently, a research team led by Prof. CHEN Ping, Prof. GUO Jianping and Associate Prof. WANG Qianru from Dalian Institute of Chemical Physics (DICP) has applied hydride materials to catalytic selective hydrogenation reactions, achieving chemoselective hydrogenation of quinolines and stereoselective hydrogenation of internal alkynes, respectively.Selective hydrogenation reactions have long been...
The activation and valorization of inert molecules, such as dinitrogen (N2), alkanes, and alkenes, for the synthesis of nitrogen-containing organic compounds have long been a highly sought-after goal in chemistry. However, it remains highly challenging due to the exceptional stability of the N≡N and C-H bonds, as well as the difficulty in achieving their cooperative activation under mild con...
With the increasing demand for sustainable energy solutions, all-solid-state potassium metal batteries (PMBs) are gaining significant interest as a viable alternative to conventional lithium-based systems owing to the natural abundance and high theoretical energy density of potassium. Nevertheless, the advancement of efficient PMBs is still hindered by the lack of suitable electrolytes.Recently...
Hydride ion (H⁻), with their low mass and high redox potential, are considered promising charge carriers for next-generation electrochemical devices. However, the lack of efficient electrolyte with fast hydride ion conductivity, thermal stability, and electrode compatibility has hindered their practical applications.In a study published in Nature, Prof. CHEN Ping's group from the Dalian Instit...
