摘要

全固态电池（ASSB）技术具有极高的安全性和能量密度，是最有前途的储能方法之一。然而，阴极结构/形态/组成/电导率演化对电化学性能的不利影响极大地限制了全固态电池的发展。为了详细研究这些阴极动态演化过程和 ASSB 的劣化机制，原位透射电子显微镜（TEM）技术已被广泛引入 ASSB 研究中。本文讨论了通过原位 TEM 对多类型 ASSB 阴极动态演化的最新重要科学发现，并强调了原位 TEM 以更高空间分辨率分析 ASSB 阴极所面临的关键挑战。最后，还展望了原位 TEM 监测 ASSB 多尺度电化学机械演变的未来发展方向。本综述将加深对阴极动态机制的基本理解，并为 ASSB 原位 TEM 的优化和发展带来新的机遇。

In Situ Transmission Electron Microscopy Advancing Cathodal Dynamic Visualization in All-Solid-State Battery

All-solid-state battery (ASSB) technology is one of the most promising approaches to energy storage due to its great safety and energy density. However, the detrimental effects of cathodal structure/morphology/composition/conductivity evolution on electrochemical performance significantly restrict the development of ASSBs. To elaborately investigate these cathodal dynamic evolution processes and deterioration mechanisms of ASSBs, in situ transmission electron microscopy (TEM) technology has been extensively introduced into the ASSB research. This paper discusses the latest important scientific discoveries toward cathodal dynamic evolution in multitype ASSBs through in situ TEM and highlights key challenges for in situ TEM to analyze ASSB cathodes with a higher spatial resolution. Lastly, insights for future directions of in situ TEM monitoring multiscale electro-chemo-mechanical evolution of ASSBs are prospectively provided. This Review will deepen the fundamental understanding of cathodal dynamic mechanisms and open new opportunities for the optimization and development of in situ TEM in ASSBs.
