Abstract: Li-ion batteries are the most popular portable power source in modern life and promises a broad range of application field, because of its advantages of high energy density, long cycle life, safety, and so on. In order to further improve lithium ion battery and promote its practical process, the study of electrode reaction mechanism is necessary. Atomic force microscope (AFM) can detect the micromorphology of the electrode surface in real time by the interaction between the tip atom and the electrode surface atom. The physical and chemical information of electrode surface is provided on nanometer scale, which provides experimental basis for the optimization modification of electrode material and electrolyte. In this paper, the latest applications of AFM in Li-ion batteries are reviewed, including the morphology changes of electrode materials under electrochemical reaction conditions, nano-mechanical properties and electrical properties, etc. It is concluded that AFM will further promote the research progress of lithium ion batteries.
