The rapid advancement of wearable electronics has driven significant interest in the development of wearable energy storage technologies. Among them, aqueous zinc ion batteries (ZIBs) have gained considerable attention as promising candidates for portable and wearable applications. In particular, aqueous fiber-shaped ZIBs offer distinctive advantages, such as miniaturization, flexibility, and wearability, making them especially suitable for powering next-generation wearable devices. This review provides a comprehensive overview of the recent advances in aqueous fiber-shaped ZIBs, focusing on the fabrication of fiber-based electrodes and various battery configurations. In addition, we highlight the evolution of fiber-shaped ZIBs from single-function to multi-function systems, exploring their potential for diverse applications. The review also addresses the key challenges in this field and discusses future research directions to drive the further development of aqueous fiber-shaped ZIBs.
