祝贺！中国科学家成功开发首例

Core Viewpoint - The research team from Dalian Institute of Chemical Physics has developed a novel core-shell structure hydrogen anion electrolyte and successfully constructed the first prototype hydrogen anion battery, marking a significant advancement in clean energy technology [1][2]. Group 1: Hydrogen Anion Electrolyte Development - The hydrogen anion is identified as a unique and highly reactive energy carrier, with the highest electron density among hydrogen forms, which includes hydrogen cations and hydrogen atoms [1]. - The research on hydrogen anion conduction began in 2018, leading to the development of a room-temperature superfast hydrogen anion conductor in 2023 through a strategy of "lattice distortion suppression of electronic conductivity" [1]. - A new composite hydride material was created by coating cerium hydride (CeH3) with barium hydride (BaH2), exhibiting rapid hydrogen anion conduction, excellent thermal stability, and electrochemical stability, making it an ideal electrolyte material [1]. Group 2: Prototype Hydrogen Anion Battery - Utilizing the new hydrogen anion electrolyte, the team assembled the first hydrogen anion prototype battery using sodium aluminum hydride (NaAlH4) as the positive electrode and cerium dihydride (CeH2) as the negative electrode [2]. - The prototype battery achieved a voltage of 1.9 volts and successfully powered an LED light, demonstrating the feasibility of hydrogen anion batteries for electronic devices [2]. - This new energy storage technology has the potential to play a significant role in large-scale energy storage, hydrogen storage, mobile power sources, and specialized power supplies in the future [2].
