This manuscript mainly proposed an effective method to well disperse the composite conductive agent which is composed of carbon nanotubes (CNTs) and graphene (Gr) in lithium-ion battery (LIB) slurry. Electrochemical Impedance Spectroscopy (EIS), Scanning Electron Microscopy (SEM) and gravitational sedimentation (GS) are employed to characterize the electrochemical, morphological and stability characterizations of LIB slurry, respectively. Specifically, electrochemical characterizations of LIB electrode slurries are performed by fitting Nyquist plots with a 10-parameter EEC, and quantitative morphological analysis of SEM images is conducted using a Mask R-CNN instance segmentation algorithm, both of which were proposed in our prior published research works. Consequently, the dispersion characterizations of LIB slurry are able to be summarized as follows: LiCoO2 particles are well dispersed in LIB slurry at φcom2 = 0.5%, by contrast, the composite conductive agent achieves superior coating and networking of LiCoO2 particles under the conditions of both φcom2 = 0.5% and mCNTs:mGr = 4:1, due to the maximized CNTs-Gr synergistic effect. Meanwhile, the formed three-dimensional "long-range" conductive network maintains the stability of its internal skeleton structure during the sedimentation of LIB slurry. This finding holds significant potential to advance the application of CNTs/Gr composite conductive agents in LIB slurry.
