    <jats:title>Abstract</jats:title><jats:p>Managing safety and supply‐chain risks associated with lithium‐ion batteries (LIBs) is an urgent task for sustainable development. Aqueous proton batteries are attractive alternatives to LIBs because using water and protons addresses these two risks. However, most host materials undergo large volume changes upon H<jats:sup>+</jats:sup> intercalation, which induces intraparticle cracking to accelerates parasitic reactions. Herein, we report that Mo<jats:sub>3</jats:sub>Nb<jats:sub>2</jats:sub>O<jats:sub>14</jats:sub> bronze exhibits reversible H<jats:sup>+</jats:sup> intercalation (200 mAh g<jats:sup>−1</jats:sup>) with a Coulombic efficiency of 99.7 % owing to near‐zero volume change and solid‐solution‐type phase transition. Combination of experimental and theoretical analyses clarifies that rotation and shrinkage of open tunnels, which consist of flexible corner‐sharing Mo/NbO<jats:sub><jats:italic>n</jats:italic></jats:sub> polyhedra, relieve local structural distortions upon H<jats:sup>+</jats:sup> intercalation to suppress intraparticle cracking. The prototype full cell of an aqueous proton battery with a Mo<jats:sub>3</jats:sub>Nb<jats:sub>2</jats:sub>O<jats:sub>14</jats:sub> anode operates stably over 1000 charge/discharge cycles. This study reveals the importance of implementing distortion‐relieving voids in host materials to reduce volume change upon charge/discharge.</jats:p>

    Ab initio calculations were carried out to predict lattice constants, elastic stiffness constants, spontaneous polarization, piezoelectric constants, and band structure of virtually wurtzite (wz)-MgO. The ground-state properties for both wz-ZnO and wz-MgO were computed using the pseudopotential-planewave method in conjunction with the local density approximation adding the Hubbard parameter to density functional theory. From the results of fitting to reliable in-plane and out-of-plane lattice constants for strain-free and perfectly pseudomorphic wz-MgxZn1−xO alloys, the elastic stiffness constant C33 of the alloy system is revealed to deviate from Vegard's law. The validity of other calculated results for virtually wz-MgO is discussed based on the physical meaning and accuracy, making a comparison with the results shown in previous reports.
