With the development of society, there have growing demand for large-capacity、 secure、 reliable and fast charging batteries.Because of high voltage、 good cycle performance、 high energy density and environmental friendly, Lithium-ion batteries are becoming the current hotspot ofthe research.The electrochemical performance degradation is closely related to the mechanics failure of material and structure.Layer electrode is the most common form of the lithium ion battery electrode, we explore the couple performance of electrochemical and mechanics.In this study, we get the in-situ measurement of deformation process of the cantilever-type graphite anode in the charging and discharging process using the CCD camera ,getting the relationship between the curvature and the SOC(state of charge) and finding the electrode curvature increases linearly with the SOC.By further analysis of the data,we also find that the Young's modulus of the graphite material will change during the Lithiated process.Within a certain range it increaselinearly.By charge-discharge cycles, we frnd the presence of unrecoverable deformation of graphite anode.Unrecoverable degree increases with the number of charge-discharge cycles.Larger SOC would cause greater damage of electrode.In addition, the experiment also tracked the color change with the state of charge and discharge, finding an evolution of Black-Blue-Brown-Red-Gold.The main purpose of this experiment is giving a new experiment method to get an in-situ measurement of the electrode materiai performance.
