Hydrogen ions are ideal charge carriers for rechargeable batteries due to their small ionic radius and wide availability. In their Communication (DOI: 10.1002/anie.201803664), C. Yan et al. explore the redox chemistry of MoO₃ for ultrafast hydrogen‐ion storage by ex situ X‐ray diffraction, photoelectron spectroscopy and reflection electron energy loss spectroscopy. The techniques have been used to identify the conversion reaction for the first hydrogen‐ion intercalation process and highly reversible redox reactions during the subsequent cycling.

三氧化钼的氧化还原化学用于超快氢离子存储

氢离子具有较小的离子半径和广泛的可用性，因此它们是可再充电电池的理想电荷载体。在他们的交流中（DOI：10.1002 / anie.201803664），C.Yan等人。通过异位X射线衍射，光电子能谱和反射电子能量损失能谱研究MoO ₃用于超快氢离子存储的氧化还原化学。该技术已被用于识别第一个氢离子嵌入过程的转化反应和随后循环中高度可逆的氧化还原反应。
