Aqueous zinc-ion batteries (ZIBs) have attracted considerable research attention recently owing to their superior features. However, various critical issues, such as insufficient energy density, poor rate capability, short cycle life, and overlooked mechanical stability, seriously impede their practical application. Although numerous efforts have been devoted to ZIBs improvement, their performance boost is usually unsatisfactory and one-sided. Herein, a simple and versatile strategy is proposed to simultaneously address these issues through synergistic dual structural regulation of the electrodes. The structural orientation regulation of electrode not only facilitate electrolyte diffusion and ion transfer, but also make the electric field distribution and Zn²⁺ ion flux more uniform. Consequently, the resulting ZIBs exhibit great rate capability and stunning cycling stability (around 0.0003% of attenuation per cycle). On this basis, the further structural size regulation of electrode endues the ZIBs with both ultrahigh MnO₂ loading (202.53 mg cm⁻³) and remarkable volumetric energy density (43.11 mWh cm⁻³), outperforming most of the state-of-the-art batteries of this kind. Additionally, the tenacious electrodes endow the fabricated ZIBs with coveted flexibility, compressibility, and extremely high safety, well suited to the needs of wearable electronics. This work provides a much more facile and promising way for the design of advanced ZIBs with excellent electrochemical performance and unparalleled mechanical toughness.

水系锌离子电池（ZIBs）由于其优越的性能最近引起了广泛的研究关注。然而，能量密度不足、倍率性能差、循环寿命短、机械稳定性被忽视等各种关键问题严重阻碍了它们的实际应用。尽管为 ZIB 的改进付出了很多努力，但它们的性能提升通常并不令人满意且是片面的。在此，提出了一种简单而通用的策略，通过电极的协同双重结构调节同时解决这些问题。电极的结构取向调控不仅有利于电解质扩散和离子转移，而且使电场分布和Zn ²⁺离子流更均匀。因此，由此产生的 ZIB 表现出出色的倍率性能和惊人的循环稳定性（每个循环衰减约 0.0003%）。在此基础上，电极的进一步结构尺寸调节使 ZIBs 具有超高 MnO ₂负载量（202.53 mg cm ^-3）和显着的体积能量密度（43.11 mWh cm ^-3)，优于大多数同类最先进的电池。此外，坚韧的电极赋予制造的 ZIBs 令人垂涎的灵活性、可压缩性和极高的安全性，非常适合可穿戴电子产品的需求。这项工作为设计具有优异电化学性能和无与伦比的机械韧性的先进 ZIBs 提供了一种更加简便和有前途的方法。
