Scalable Production of Motion‐Enabled Self‐Charging Power Textiles with Highly Durable Zinc‐Ion Fiber Batteries

ABSTRACT

To meet the pressing need for convenient power in wearable electronics, this work presents self‐charging power textiles based on an integrated harvesting‐management‐storage strategy. The system employs fiber‐shaped triboelectric nanogenerators (F‐TENGs) paired with an energy management module to harvest energy from motion. Meanwhile, a Zn ²⁺ ‐assisted in situ rapid cross‐linking strategy using a sodium alginate/polyvinyl alcohol (SA/PVA) hydrogel electrolyte enables scalable production of fiber‐shaped zinc‐ion batteries (F‐ZIBs). This hydrogel electrolyte establishes continuous Zn ²⁺ conduction pathways, allowing the F‐ZIB to retain 95.7% capacity after 100 cycles at 0.2 A g ⁻¹ and 86.5% after 1,000 cycles at 2 A g ⁻¹ , with good environmental tolerance. The composite yarns for F‐TENGs are fully compatible with large‐scale manufacturing. By co‐weaving F‐ZIBs and F‐TENGs, the power textile demonstrates synergistic, long‐term operation capable of powering commercial devices such as smartphones, smart rings, and AI glasses. This study provides an accessible and universal energy solution for next‐generation self‐powered wearable systems.
