Proton intercalation of Mo₃Nb₂O₁₄ bronze occurs with near-zero volume change, which arises from rotation and shrinkage of the flexible MOn framework (M = Mo, Nb) as reported by Kosuke Kawai et al. in their Research Article (e202410971). As a result, the Mo₃Nb₂O₁₄ particle maintains high crystallinity after repeating proton (de)intercalation, which contributes to high Coulombic efficiency and long-term charge/discharge operation of an aqueous proton battery.

封面内页：质子嵌入到开隧道青铜相中，体积变化接近零


Mo₃Nb₂O₁₄ 青铜的质子嵌入以接近零的体积变化发生，这是由柔性 MOn 框架 （M = Mo， Nb） 的旋转和收缩引起的，正如 Kosuke Kawai 等人在其研究文章 （e202410971） 中报告的那样。因此，Mo₃Nb₂O₁₄ 颗粒在重复质子（脱）嵌后保持高结晶度，这有助于水系质子电池的高库仑效率和长期充放电操作。
