Metal anodes have attracted much interest in metal batteries because of their high theoretical capacity and outstanding electrochemical performance. However, practical applications are often limited by polarization effects, leading to reaction capacity, lower energy efficiency, shorter cycle life. Herein, a hierarchical porous nickel (Ni) is proposed as promising anode with extremely low at current density capacity. This Ni has large specific surface area, fast kinetics can be realized. As result, this capable achieving an voltage ~10 mV 40 mA cm−2@40 mAh cm−2. In contrast, the plate ~100 Additionally, symmetrical coin cells made unique way maintained for 800 h cm−2 400 80 cm−2@80 that achieve density/high provides new direction developing high-performance batteries.

Abstract Rechargeable zinc‐ion batteries (ZIBs) have gained significant attention as potential next‐generation energy storage systems, owing to their inherent safety, environmental benignity, and cost‐effectiveness. However, the substantial electrostatic repulsion of Zn ion results in a sluggish kinetics for its insertion into cathode material. Meanwhile, formation hydrated ionic groups with increased mass volume aqueous electrolyte further hampers transport ability zinc ions, significantly impacting overall electrochemical performance (including capacity, density, rate‐capability, cyclability) batteries. This review systematically summarized recent progress regulation strategy kinetics. The as‐reported mechanisms are introduced ZIBs (Zn 2+ insertion/extraction mechanism, H + or 2 O/ co‐insertion/extraction conversion reaction coordination mechanism). Then, material design fast including soft lattice construction, doping effects, defect introduction, morphology control, interface is summarized. Finally, it concluded future research directions, such high‐entropy design, multi‐scale simulation, machine study, providing roadmap developing high‐performance at ultralow operation temperatures.
