Abstract

Metal-iodine batteries have attracted widespread attention due to their long cycle life, high energy density, remarkable charging capability and low self-discharge rate. Nevertheless, this development is hampered by the challenges of the iodine cathode and metal anode, including the hydrogen evolution reaction (HER), sluggish kinetics, shuttle effect of polyiodine ion at the cathode and dendrite formation, corrosion and passivation at the anode. This review summarizes recent developments in metal-iodine batteries, including zinc-iodine batteries, lithium-iodine batteries, sodium-iodine batteries, etc. The challenges in the cathode, anode, electrolyte and separator of metal-iodine batteries are discussed, along with the corresponding design and synthesis strategies and specific methods to improve the electrochemical performance. Selecting appropriate cathode hosts, constructing surface protective layers, adding anode additives, making three-dimensional anode designs and employing better electrolytes and functional separators to obstruct the production and shuttling of polyiodine ions are highlighted. Finally, future guidelines and directions for the development of metal-iodine batteries are proposed.

金属碘电池的进展：进展与展望

金属碘电池因其循环寿命长、能量密度高、充电能力强、自放电率低等特点而受到广泛关注。然而，这一发展受到了碘阴极和金属阳极的挑战，包括析氢反应（HER）、动力学迟缓、阴极多碘离子的穿梭效应和阳极枝晶的形成、腐蚀和钝化。本文综述了金属碘电池的研究进展，包括锌碘电池、锂碘电池、钠碘电池等。讨论了金属碘电池在阴极、阳极、电解液和隔膜等方面面临的挑战，提出了相应的设计合成策略和提高电化学性能的具体方法。选择合适的阴极主体，构建表面保护层，添加阳极添加剂，进行三维阳极设计，以及采用更好的电解质和功能隔膜来阻止多碘离子的产生和穿梭。最后，对今后金属碘电池的研究方向和发展方向进行了展望。图形抽象
