    <jats:title>Abstract</jats:title><jats:p>Prussian blue (PB) is regarded as a promising cathode for sodium‐ion batteries because of its sustainable precursor elements (e.g., Mn, Fe), easy preparation, and unique framework structure. However, the unstable structure and inherent crystal H<jats:sub>2</jats:sub>O restrain its practical application. For this purpose, a self‐constructed trace Mg<jats:sup>2+</jats:sup>/K<jats:sup>+</jats:sup> co‐doped PB prepared via a sea‐water‐mediated method is proposed to address this problem. The Mg<jats:sup>2+</jats:sup>/K<jats:sup>+</jats:sup> co‐doping in the Na sites of PB is permitted by both thermodynamics and kinetics factors when synthesized in sea water. The results reveal that the introduced Mg<jats:sup>2+</jats:sup> and K<jats:sup>+</jats:sup> are immovable in the PB lattices and can form stronger K‒N and Mg‒N Coulombic attraction to relieve phase transition and element dissolution. Besides, the Mg<jats:sup>2+</jats:sup>/K<jats:sup>+</jats:sup> co‐doping can reduce defect and H<jats:sub>2</jats:sub>O contents. As a result, the PB prepared in sea water exhibits an extremely long cycle life (80.1% retention after 2400 cycles) and superior rate capability (90.4% capacity retention at 20 C relative to that at 0.1 C). To address its practical applications, a sodium salts recycling strategy is proposed to greatly reduce the PB production cost. This work provides a self‐constructed Mg<jats:sup>2+</jats:sup>/K<jats:sup>+</jats:sup> co‐doped high‐performance PB at a low preparation cost for sustainable, large‐scale energy storage.</jats:p>

    <jats:p>The dynamic charge density of KZnB<jats:sub>3</jats:sub>O<jats:sub>6</jats:sub>, which contains edge-sharing BO<jats:sub>4</jats:sub> units, has been characterized using laboratory and synchrotron X-ray diffraction techniques. The experimental electron density distribution (EDD) was constructed using the maximum-entropy method (MEM) from single crystal diffraction data obtained at 81 and 298 K. Additionally, MEM-based pattern fitting (MPF) method was employed to refine the synchrotron powder diffraction data obtained at 100 K. Both the room-temperature single crystal diffraction data and the cryogenic synchrotron powder diffraction data reveal an intriguing phenomenon: the edge-shared B<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> ring exhibits a significant charge density accumulation between the O atoms. Further analysis of high-quality single crystal diffraction data collected at 81 K, with both high resolution and large signal-to-noise ratio, reveals no direct O–O bonding within the B<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> ring. The experimental EDD of KZnB<jats:sub>3</jats:sub>O<jats:sub>6</jats:sub> obtained aligns with the results obtained from <jats:italic>ab-initio</jats:italic> calculations. Our work underscores the importance of obtaining high-quality experimental data to accurately determine EDDs.</jats:p>
