摘要:

传统的锂金属电池存在电解液易泄漏、 易燃等安全隐患, 因此开发不燃性全固态电解质对于解决锂金属电池安全问题至关重要, 而如何有效降低固体电解质与电极之间的界面电阻是发展高性能全固态锂金属电池的关键. 针对如何优化全固态锂金属电池表界面的问题, 本文综述了全固态锂金属电池电极和电解质表面修饰的最新研究进展, 对提高界面接触和降低界面电阻的传统方法进行了探讨, 分析并点评了新型的表面修饰技术, 为进一步提高全固态锂金属电池的综合性能提供新思路. 最后, 对全固态锂金属电池的研究前景进行了展望.

Abstract:

Owing to the potential safety hazards such as electrolyte leakage and flammability of traditional lithium batteries, nonflammable all-solid-state electrolytes are considered to be ideal electrolyte candidates for lithium batteries. However, how to effectively reduce the interface resistance between the solid-state electrolyte and the electrode is the key to the development of all-solid-state lithium batteries. In this article, we review the research progress in surface modification of all-solid-state lithium battery electrodes and electrolytes. The classic methods of improving the interface contact and reducing the interface resistance are also discussed. Based on the traditional methods, new surface modification technologies will provide new ideas for improving the performance of all-solid-state lithium batteries in the future.

Key words: All-solid-state lithium battery, Surface and interface modification, Electrode material, All-solid-state electrolyte
