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

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 Zn²⁺-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 Zn²⁺ 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.
