Abstract

The relentless pursuit of sustainable and safe energy storage technologies has driven a departure from conventional lithium-based batteries toward other relevant alternatives. Among these, aqueous batteries have emerged as a promising candidate due to their inherent properties of being cost-effective, safe, environmentally friendly, and scalable. However, traditional aqueous systems have faced limitations stemming from water's narrow electrochemical stability window (~1.23 V), severely constraining their energy density and viability in high-demand applications. Recent advancements in decoupling aqueous batteries offer a novel solution to overcome this challenge by separating the anolyte and catholyte, thereby expanding the theoretical operational voltage window to over 3 V. One key component of this innovative system is the ion-selective membrane (ISM), acting as a barrier to prevent undesired crossover between electrolytes. This review provides a comprehensive overview of recent advancements in decoupling aqueous batteries, emphasizing the application of various types of ISMs. Moreover, we summarize different specially designed ISMs and their performance attributes. By addressing the current challenges ISMs face, the review outlines potential pathways for future enhancement and development of aqueous decoupling batteries.

水性去耦电池：探索功能性离子交换膜的作用

对可持续和安全储能技术的不懈追求，促使人们从传统的锂电池转向其他相关替代品。其中，水性电池因其固有的成本效益高、安全、环保和可扩展等特性，已成为一种前景广阔的候选方案。然而，由于水的电化学稳定性窗口较窄（约 1.23 V），传统的水性系统面临着种种限制，严重制约了其能量密度和在高需求应用中的可行性。最近在解耦水电池方面取得的进展为克服这一挑战提供了一种新颖的解决方案，即分离阳离子和阴离子，从而将理论工作电压窗口扩大到 3 V 以上。这种创新系统的一个关键部件是离子选择膜（ISM），它是防止电解质之间发生意外交叉的屏障。本综述全面概述了去耦水性电池的最新进展，强调了各种类型 ISM 的应用。此外，我们还总结了各种专门设计的 ISM 及其性能属性。通过探讨 ISM 当前面临的挑战，综述概述了水性解耦电池未来改进和发展的潜在途径。
