An international research collaboration, from Sun Yat-sen University, South China University of Technology, University of Liverpool and JiangSu CheeShine Performance Materials Co., has developed a mechanically adaptive artificial interphase for ultrafast zinc metal batteries. By constructing a spider-web-like nitrile butadiene rubber (NBR) nanofiber interphase, the researchers achieved synergistic regulation of homogeneous Zn²⁺ transport, free-water blocking, and interfacial deformation buffering. This strategy transforms unstable zinc growth into a uniform and confined surface deposition process. Based on this interphase, Zn//Zn symmetric cells can operate stably for more than 6,000 hours, while Zn//V₂O₅ full cells deliver stable cycling for 20,000 cycles at an ultrahigh rate of 50 A g^-1, providing a new interfacial engineering strategy for safe and high-power aqueous zinc batteries.

Hydrogel electrolytes are pivotal for flexible zinc-ion batteries (ZIBs) yet suffer from an intrinsic trade-off between mechanical robustness and ionic conductivity. Herein, drawing inspiration from the “adhesion-conduction” architecture of spider webs, we developed a hierarchical hydrogel electrolyte (MTP) by incorporating tannic acid (TA)-modified MXene nanosheets (MT) into a polyacrylamide (PAM) skeleton to construct uniform 3D ion-conductive pathways. This bioinspired hierarchy serves a dual function: The PAM framework ensures mechanical integrity, while the MT network creates directed low-resistance channels for Zn²⁺ transport. Specifically, the dense array of polar groups on MXene and phenolic hydroxyls on TA act as “sticky sites”, which accelerate desolvation kinetics and homogenize Zn²⁺ flux. Consequently, the MTP electrolyte achieves an impressive ionic conductivity of 27.69 mS cm⁻¹ and a high Zn²⁺ transference number of 0.833. Enabled by this design, Zn//Zn symmetric cells demonstrate an ultralong lifespan of 4600 h (> 6 months) at 0.5 mA cm⁻²/0.5 mAh cm⁻². Furthermore, Zn//Z-VO full cells exhibit outstanding cyclability, retaining 74.5% capacity after 2000 cycles at 2 A g⁻¹ and maintaining durable operation for over 10,000 cycles at 5 A g⁻¹. This work successfully translates a biological blueprint into a practical strategy for resolving the kinetic and stability challenges in high-performance flexible ZIBs.
