Prussian blue analogs (PBAs) are promising candidates for aqueous Zn-ion batteries due to their unique open-framework structures. However, they suffer from limited capacity and severe decay originating insufficient redox sites structural instability. Herein, Cu-substituted Mn-PBA double-shelled nanoboxes (CuMn-PBA DSNBs) prepared by tannic acid etching cation exchange approaches demonstrated efficient Zn ion storage. The hollow structures can expose abundant active alleviate the volume change during cycling test. Moreover, partial Cu substitution induced Mn vacancies might inhibit Jahn-Teller distortions of Mn-N6 octahedra, thus contributing prolonged lifespan. As a result, CuMn-PBA DSNBs exhibit high reversible capacity, decent rate performance superior stability 2000 cycles. Furthermore, ex situ characterizations reveal that charge storage mechanism mainly involves reactions transition metals Zn2+ insertion/extraction processes.
