Zinc‐based batteries have a high capacity and are safe, cost‐effective, environmentally‐friendly, and capable of scalable production. However, dendrite formation and poor reversibility hinder their performance. Metal‐organic framework (MOF)‐based Zn anodes are made by wet chemistry to address these issues. These MOF‐based anodes exhibit high efficiency during Zn plating‐stripping and prevent dendrite formation, as shown by ex situ SEM analysis. The practicality of the MOF‐based anodes is demonstrated in aqueous Zn ion batteries, which show improved performance including specific capacity, cycle life, and safety relative to the pristine Zn anode due to their hydrophilic and porous surface. These results, along with the easy scalability of the process, demonstrate the high potential of MOF‐modified Zn anodes for use in dendrite‐free, higher‐performance, Zn‐based energy storage systems.

水性锌离子电池的金属有机框架集成阳极

锌基电池具有高容量，并且安全，具有成本效益，对环境友好，并具有可扩展的生产能力。但是，枝晶的形成和可逆性差阻碍了它们的性能。基于金属有机骨架（MOF）的Zn阳极是通过湿化学法制造的，旨在解决这些问题。这些MoF基阳极在异物SEM分析中显示，在镀锌剥离过程中表现出高效率并防止了枝晶的形成。水性Zn离子电池证明了基于MOF的阳极的实用性，由于其亲水性和多孔性，与原始的Zn阳极相比，其性能有所改善，包括比容量，循环寿命和安全性。这些结果以及该工艺的简单可扩展性证明了MOF改性的Zn阳极在无枝晶，
