Characterization of nano-scale interface in lithium batteries using epitaxial model electrodes

用X射线表面散射测量方法研究了锂电池的界面反应。电极表面的原子排列在浸泡在电解质中时改变，并且随后在第一充电过程中施加电压时重构。表面结构的机械和技术发展对于改善新一代电池的功率特性和循环性能具有相当重要的意义。

Interfacial reactions of lithium batteries have been determined by in situ X-ray surface scattering measurements using epitaxial thin-films electrodes. The atomic arrangements of electrode surfaces change on being soaked in the electrolyte, and are subsequently reconstructed when a voltage is applied in the first charge process. Mechanical and technical development of surface structures is of considerable importance for improving the power characteristics and cyclability of new-generation batteries.
