## Description

- description: 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+ intercalation, which induces intraparticle cracking to accelerates parasitic
    reactions. Herein, we report that Mo3Nb2O14 bronze exhibits　reversible H+ intercalation
    (200 mAh g−1) 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/NbOn polyhedra, relieve local structural distortions
    upon H+ intercalation to suppress intraparticle cracking. The prototype full cell
    of an aqueous proton battery with a Mo3Nb2O14 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.
