Fiber-shaped aqueous zinc ion batteries for wearable energy solutions

The rising popularity of smart wearable electronic devices has spurred advancements in portable battery technology, particularly in the realm of aqueous zinc-ion batteries (AZIBs). This paper explores the advancements in AZIBs, and highlights their advantages - they are high in energy density, very safe, and cost effective. Notably, fiber-shaped AZIBs can be constructed with various structural configurations to meet different application requirements and seamlessly integrated into wearable products due to their compatibility with different types of fabrics. By weaving fiber-shaped AZIBs into textiles, a new type of energy textile can be obtained, which is flexible and breathable, with miniaturization potential previously unattainable with conventional power sources.
