由于使用水基电解质，水系锌离子电池 (ZIB) 因安全、生产成本低廉和生态友好而享有盛誉。然而，限制ZIBs发展的主要因素是枝晶沉积对锌负极的负面影响以及普通正极如锰基和钒基正极的溶解。已经使用各种技术来解决这些问题，包括调节电解质浓度或溶剂化结构，开发涂层或集电器以减少阳极枝晶生长，以及提高阴极的结构稳定性。最近，功能化分离策略作为提高 ZIB 性能的有效方法而受到欢迎。使用功能化隔膜也是一种实用技术，可以通过用功能化隔膜替代通常厚且昂贵的玻璃纤维隔膜来节省成本并提高电池的体积能量密度。ZIBs 中功能化分离器的开发是正在进行的研究主题，这项工作以系统的方式展示了最新的发现，重点关注了效果和制备或修改它们的方法。最后，简要说明了当前功能化隔膜发展的局限性和未来潜力。这项工作以系统的方式展示了最新的发现，重点关注影响和准备或修改它们的方法。最后，简要说明了当前功能化隔膜发展的局限性和未来潜力。这项工作以系统的方式展示了最新的发现，重点关注影响和准备或修改它们的方法。最后，简要说明了当前功能化隔膜发展的局限性和未来潜力。

Functionalized Separator Strategies toward Advanced Aqueous Zinc-Ion Batteries

Aqueous zinc-ion batteries (ZIBs) enjoy a good reputation for being safe, affordable to produce, and ecologically friendly due to the use of water-based electrolytes. The main factors restricting the development of ZIBs, however, are the negative effects of dendrite deposition on the zinc anode and the dissolution of common cathodes such as Mn and V-based cathodes. Various techniques have been used to address these issues, including regulating the electrolyte concentration or solvation structure, developing a coating or current collector to lessen anode dendrite growth, and improving the structural stability of the cathode. Recently, functionalized separator strategies have gained popularity as effective ways to improve ZIB performance. The use of a functionalized separator is also a practical technique to save costs and increase the volumetric energy density of the battery by substituting a functionalized separator for the usual thick and expensive glass fiber separator. The development of functionalized separators in ZIBs is the subject of ongoing research, and this work presents the most recent findings in a systematic manner, focusing on both the effects and the methods to prepare or modify them. Finally, a brief explanation of the constraints and future potential of current functionalized separator development is provided.
