Surface structures analysis and function control for lithium battery reaction

用X射线表面散射测量方法研究了锂电池的界面反应。界面结构决定了锂过量层状材料电极的功率密度和稳定性。Li3PO4固体电解质的表面改性提高了电池运行时电极结构的稳定性。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 interracial structures determine the power density and the stability of lithium-excess layered material electrodes. Surface modification by Li3 PO4 solid electrolyte improved the stability of the electrode structure upon battery operations. Mechanical and technical development of surface structures is of considerable importance for improving the power characteristics and cyclability of new-generation batteries.
