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.
