祝贺！中国科学家成功开发首例——

Core Viewpoint - A new type of hydrogen negative ion electrolyte has been developed by the Dalian Institute of Chemical Physics, which has significant potential for clean energy applications and has been successfully demonstrated in a prototype battery [1][2]. Group 1: Development of Hydrogen Negative Ion Electrolyte - The research team initiated the study of hydrogen negative ion conduction in 2018 and proposed a strategy to suppress electronic conductivity through lattice distortion in 2023 [1]. - A novel core-shell structured composite hydride material was created using barium hydride (BaH2) to coat cerium hydride (CeH3), exhibiting rapid hydrogen negative ion conduction at room temperature along with excellent thermal and electrochemical stability [1]. Group 2: Prototype Battery Construction - Utilizing the new hydrogen negative ion electrolyte, the team assembled the first 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, marking a transition from theoretical model to laboratory prototype [2]. - This hydrogen negative ion battery technology is expected to play a crucial role in large-scale energy storage, hydrogen storage, mobile power sources, and specialized power applications in the future [2].
