3D Printed Low-Tortuosity and Ultra-Thick Hierarchical Porous Electrodes for High-Performance Wearable Quasi-Solid-State Zn-VOH Batteries.

ABSTRACT: Rechargeable aqueous Zn-ion batteries have received considerable attention in energy storage systems owing to their merits of high safety, low cost, and excellent rate performance. However, the unsatisfactory areal energy density and poor cycling performance hinder their practical applications. Herein, the V₅O₁₂·6H₂O (VOH) nanosheet arrays and Zn nanoflake arrays growing on the 3D-printed reduced graphene oxide/carbon nanotubes (3DP-rGO/CNTs) microlattices employing the electrodeposition technique, and further serve as the cathode and anode for 3D-printed aqueous Zn-VOH battery, respectively. Benefiting from 3D-printed low-tortuosity and ultra-thick hierarchical porous electrodes, the battery-type VOH-based cathode enables fast Zn²⁺ reaction kine
