The inside cover picture shows that in situ electrochemical atomic force microscopy is performed to clarify the correlation between the decomposition behavior of toroidal lithium peroxide (Li₂O₂) and the charging rate in a working Li-O₂ battery. In situ observation reveals that a low charge rate promotes the decomposition of toroidal Li₂O₂ sufficiently, while a larger charge rate accelerates the decomposition occurring at the Li₂O₂/electrode interface, causing the irreversible capacity degradation. More details are given in the article by Wen et al. on page 2668—2672.

内封面图片

内盖图片显示，进行原位电化学原子力显微镜检查以阐明环形过氧化锂 (Li ₂ O ₂ )的分解行为与工作中的 Li-O ₂电池的充电率之间的相关性。原位观察表明，低充电速率充分促进了环形Li ₂ O ₂的分解，而较大的充电速率加速了Li ₂ O ₂ /电极界面处发生的分解，导致容量不可逆下降。Wen等人的文章中提供了更多详细信息。第 2668-2672 页。
