High-energy-density anode materials are crucial for achieving high performance alkali metal-ion batteries (AMIBs). In situ transmission electron microscopy (TEM) enables real-time observation of microstructural changes in electrode materials and interfaces during charging/discharging, crucial for designing high-performance anodes. This paper highlights and reviews the dynamic studies of the relationship between the structure and the electrochemical performance of carbon-based composite materials used as anodes in AMIBs by in situ TEM. First, the in situ TEM technique and cell construction method are introduced, followed by an overview of in situ TEM integrates with other advanced measurement techniques. Second, the fundamental working principles of various AMIBs and the energy storage mechanisms of anode materials are explained, along with the achievable functions of in situ TEM in AMIBs. Third, from different carbon matrix structures, including carbon-supported, carbon-embedded, carbon-coated, carbon-encapsulated, and hybrid carbon-composite structures, in situ dynamic studies on the electrochemical behaviors of these carbon-based anode materials by TEM are covered in depth. Finally, a summary of the design ideas and the technical application of in situ TEM for carbon-based anode composites is provided, followed by a suggestion for current challenges and future research paths.

原位 TEM 在碱金属离子电池中碳基负极动力学研究方面的进展
高能量密度负极材料对于实现高性能碱金属离子电池 （AMIB） 至关重要。原位透射电子显微镜 （TEM） 能够实时观察充电/放电过程中电极材料和界面的微观结构变化，这对于设计高性能阳极至关重要。本文重点介绍并回顾了原位 TEM 用作 AMIB 阳极的碳基复合材料的结构与电化学性能之间关系的动力学研究。首先，介绍了原位 TEM 技术和电池构建方法，然后概述了原位 TEM 与其他先进测量技术的集成。其次，解释了各种 AMIB 的基本工作原理和负极材料的储能机制，以及 AMIB 中原位 TEM 可实现的功能。第三，从不同的碳基结构，包括碳负载、碳嵌入、碳涂层、碳封装和混合碳复合结构，深入介绍了 TEM 对这些碳基负极材料的电化学行为的原位动力学研究。最后，总结了原位透射电镜在碳基负极复合材料中的设计思路和技术应用，并对当前面临的挑战和未来的研究路径提出了建议。
