固态锂电池界面问题的研究进展
Progress on interfacial issues of solid state lithium batteries
摘要
Abstract
Compared with traditional lithium ion batteries, the solid state lithium batteries based on solid state electrolytes with features of large energy density, long cycle life and high safe reliability are one of the research hotspots in the field of energy storage. Solid state lithium batteries would be widely used in electric vehicles and portable electronics in the future. The ion conductivity is determined by the internal interface of the solid state electrolyte. Compared with the solid-liquid interfaces, the formed solid-solid interfaces between electrodes and solid electrolytes in the solid batteries exhibit higher contact resistance. Meanwhile, the interface compatibility and stability markedly affect the cycle stability and rate capability of solid state lithium batteries. Therefore, solving the interfaces issues in solid state lithium batteries is critical for realizing high performance. The research progress of various interfacial issues on solid state lithium batteries based on LLZO electrolytes was reviewed, and the perspective on the interfacial manipulation and optimization for solid state lithium batteries was prospected.关键词
