摘要:: 原子力显微镜（AFM）是表面成像技术中最重要的进展之一，它能够在纳米尺度上提供材料的局域形态、化学和物理信息。近十几年来，在AFM的原有模式上已经衍生出了调幅调频成像模式、开尔文探针力显微术、电化学应变显微术、扫描扩展电阻显微术等多种成像模式，能够提供更多的力学、电学和电化学信息。目前这些先进的显微技术已经被广泛用于储能系统，特别是锂离子电池的研究中，在纳米尺度上提供电极表面的物理化学信息，并为深入了解锂离子电池内部的电化学过程、降解机制及动态性能等提供了可靠的实验依据。综述了AFM的工作原理和工作模式，介绍了AFM在锂离子电池负极材料研究中的最新应用进展，最后展望了AFM在锂离子电池负极材料领域研究的应用前景。

Abstract:: Atomic force microscope(AFM) is one of the most important advances in surface imaging technology. It can provide local morphology, chemical and physical information of materials on the nanometer scale. In recent years, amplitude modulation-frequency modulation, Kelvin probe force microscopy, electrochemical strain microscopy, scanning spreading resistance microscopy and other imaging modes have been derived from the original mode of AFM, which can provide more mechanical, electrical and electrochemical information. At present, these state-of-the-art AFM methods have been applied to energy storage systems, specifically lithium-ion batteries. The physical and chemical information of the electrode surface is provided on the nanometer scale, which provides a reliable experimental basis for further understanding the electrochemical process, degradation mechanism and dynamic performance of lithium-ion batteries. This paper reviews the working principle and working mode of AFM, introduces the latest application of AFM in the research of the negative materials of lithium-ion batteries. Finally, the application of AFM in the field of negative materials of lithium-ion batteries is prospected.
