Abstract
In situ tracking of chemical phase transformation, mapping, and composition information of a battery with CuO as the anode was performed with quantitative analysis at sub-30 nm resolution with a 40 × 40 μm field of view using transmission X-ray microscopy combined with spectroscopy. A size-dependent and core-shell lithiation-delithiation mechanism was suggested for the electrochemical reaction.
摘要
采用透射 X 射线显微镜结合光谱学，在 40×40μm 视场下，以 30nm 以下的分辨率对以 CuO 为阳极的电池的化学相转变、映射和成分信息进行了原位跟踪和定量分析。提出了一种与尺寸相关的核壳型锂化-脱锂反应机制。
