Rapid analysis method for dispersion uniformity of solid substances in lithium ion battery slurry

The invention discloses a rapid analysis method for dispersion uniformity of solid substances in lithium ion battery slurry. The method comprises the following steps: taking just prepared slurry, quickly drying the slurry, observing the internal morphology and microstructure of the solid slurry by using a scanning electron microscope, and evaluating the dispersion uniformity of solid substances inthe slurry according to the internal morphology and microstructure of the obtained solid slurry. According to the method, the dispersion state of solid substances in a coated electrode coating can bepre-judged, the processes of coating and the like are not needed, waste of slurry can be avoided, and the method has the advantages of time saving, cost saving and the like. The method is simple andeasy to operate and implement, the result is accurate and effective, the dispersion uniformity of the solid substances in the lithium ion battery slurry can be rapidly analyzed, and experimental research and large-scale use in
