Core Viewpoint - A new type of hydrogen negative ion electrolyte has been developed by a research team from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, leading to the creation of the world's first hydrogen negative ion prototype battery, marking a significant advancement from conceptualization to experimental validation [1][2]. Group 1: Battery Development - The hydrogen negative ion battery operates similarly to lithium-ion batteries, utilizing the movement of ions between electrodes for charging and discharging, but replaces lithium ions with hydrogen negative ions [1]. - The research team employed a "core-shell structure" strategy, using barium hydride to encapsulate cerium trihydride, resulting in an electrolyte with high hydrogen negative ion conductivity, low electronic conductivity, and high stability [1]. Group 2: Performance Metrics - The prototype battery achieved a discharge capacity of 984 milliampere-hours per gram (mAh/g) and maintained a capacity of 402 mAh/g after 20 charge-discharge cycles [2]. - A stacked battery configuration was developed, increasing the voltage to 1.9 volts, successfully powering an LED light, demonstrating the feasibility of the hydrogen negative ion battery for electronic devices [2]. Group 3: Future Applications - The hydrogen negative ion battery represents a new energy storage technology path, with potential applications in large-scale energy storage, hydrogen storage, and mobile power sources [2]. - The research team plans to focus on optimizing the core materials and performance of the hydrogen negative ion battery, aiming to expand its application scenarios and support the development of green energy in China [2].
