Characterization of Li Ion Battery


Figure 3: Topography (A), resistance (B), and conductance (C) images acquired from an LIB electrode sample. Line profile (D): Topography line profile (red line, y-axis on left), resistance line profile (green, y-axis on right), and conductance line profile (blue line, y-axis on right). 3D-overlay image of topography and conductance (E).


can also be observed in the 3D-overlay image of topography and conductance (Figure 3D) acquired in the XEI mode. Both resistance and conductance images show a clear picture of the small grains surrounding the circular plateaus. It was

discovered that these small grains have lower resistivity and higher conductivity when compared to the circular plateaus. Analysis of the corresponding line profile (Figure 3E) of the topography, conductance, and resistance images confirms
