Texturing (002)‐Oriented Zinc Atop a Cotton Cloth for High‐Performance Zn‐Ion Batteries

Abstract Zn‐ion batteries emerge as a promising alternative to conventional Li‐ion batteries due to their superior environmental friendliness and high safety, making them suitable for sustainable energy storage in various applications. However, concerns persist regarding the limitations of Zn‐ion batteries, such as uncontrolled dendrite growth and side reactions. In this study, the electroplating method was employed to deposit (002) plane‐dominated textures on a modified cotton cloth substrate, which consists of a silver conductive layer atop a cotton supporting layer. The electroplating current density and time are critical for the fabrication of dense and compact (002) Zn textures. The optimized condition for this process involves a current density of 40 mA/cm 2 and an electroplating time of 30 minutes. Compared to (101)‐dominated Zn anodes, the (002)‐dominated electrode demonstrates faster deposition kinetics and lower charge transfer resistance, enabling denser and more uniform Zn deposition. Additionally, the (002)‐dominated electrode also exhibits an enhanced ability to inhibit side reactions in the mild aqueous electrolyte, further improving the lifespan of Zn‐ion batteries. This work demonstrates the feasibility of using ordinary cotton cloth as a substrate for electroplating (002)‐dominated Zn, thereby expanding the potential applications of Zn‐ion batteries.
