摘要:

原子力顯微鏡（AFM）是表面成像技術(shù)中最重要的進展之一，它能夠在納米尺度上提供材料的局域形態(tài)、化學(xué)和物理信息。近十幾年來，在AFM的原有模式上已經(jīng)衍生出了調(diào)幅�舱{(diào)頻成像模式、開爾文探針力顯微術(shù)、電化學(xué)應(yīng)變顯微術(shù)、掃描擴展電阻顯微術(shù)等多種成像模式，能夠提供更多的力學(xué)、電學(xué)和電化學(xué)信息。目前這些先進的顯微技術(shù)已經(jīng)被廣泛用于儲能系統(tǒng)，特別是鋰離子電池的研究中，在納米尺度上提供電極表面的物理化學(xué)信息，并為深入了解鋰離子電池內(nèi)部的電化學(xué)過程、降解機制及動態(tài)性能等提供了可靠的實驗依據(jù)。綜述了AFM的工作原理和工作模式，介紹了AFM在鋰離子電池負極材料研究中的最新應(yīng)用進展，最后展望了AFM在鋰離子電池負極材料領(lǐng)域研究的應(yīng)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.
