Most scholars use atomic force microscopy (AFM) to analyze battery pack materials. Because of the defects of low resolution and limited application of AFM, an atomic force microscopy system based on IPC is designed. The atomic force microscopy is constructed by the system, and the tunnel effect of quantum theory is used to construct AFM. The atomic linearity probe and battery material surface should be used as two electrodes. A certain voltage is applied between battery material and needle tip. When the distance between battery material and needle tip is very close, the tunnel current will be generated. The piezoelectric ceramic material is used to control the needle tip to scan the battery material surface. The probe is in the vertical direction of battery material. The variation of the current in the upper tunnel reflects the fluctuation of material characteristics. The characteristics of battery pack materials can be analyzed by atomic force microscopy based on IPC. The experimental results show that the average accuracy and analysis time of this method are 98.89% and 5.81ms, and the analysis effect is good. [ABSTRACT FROM AUTHOR]
