近日，365体育投注:大连化学物理研究所陈萍团队研究了一种室温可充电全固态氢化物离子电池。相关论文于2025年9月17日发表在《自然》杂志上。

作为负电荷载体，氢化物离子（H-）比阳离子更有活力，更容易极化，反应性更强。氢介导的电化学过程与现有系统有着根本的不同，它能够开发出创新的电化学装置，如可充电电池、燃料电池、电解电池和气体分离膜。

研究组开发了一种核壳氢化物3CeH3@BaH2，在环境温度下表现出快速的H-传导，在60℃以上成为超离子导体。这种氢化物使人们能够构建一种全固态可充电H−电池CeH2|3CeH3@BaH2|NaAlH4，其分别使用NaAlH4和CeH2作为阴极和阳极材料在环境条件下运行。该电池的初始比容量为984 mAh g-1，在20次循环后仍保持402 mAh g-1。使用氢离子作为电荷载流子原则上可避免形成有害金属枝晶，为清洁能源储存与转化开辟了新的研究方向。

Abstract: As a negative charge carrier, the hydride ion (H) is more energetic, polarizable and reactive than cations1. An H-mediated electrochemical process is fundamentally different from existing systems and enables the development of innovative electrochemical devices, such as rechargeable batteries, fuel cells, electrolysis cells and gas separation membranes2. Here we developed a core-shell hydride 3CeH3@BaH2, which exhibits fast H conduction at ambient temperature and becomes a superionic conductor above 60°C. This hydride allows us to construct an all-solid-state rechargeable H battery CeH2|3CeH3@BaH2|NaAlH4, which operates at ambient conditions using NaAlH4 and CeH2 as cathode and anode materials, respectively. This battery has an initial specific capacity of 984mAhg1 and retains 402mAhg1 after 20 cycles. Using hydrogen as charge carriers can avoid the formation of detrimental metal dendrites, in principle, which creates new research avenues for clean energy storage and conversion.
