Investigations of dispersion mechanism in lithium ion battery slurry has been conducted. The flow patterns in high shearing homogenizer have been performed by numerical simulation using commercial computational fluid dynamics package. A novel dispersion system of high-shear has been designed for lithium ion battery slurry, and a preliminary experimental has been conducted. From the results, utilization of the high-shear technology in the lithium ion battery slurry is beneficial to not only improve its uniformity, but also shorten the dispersion time greatly. All the conclusions in this investigation provide technology support for applying high-shear technology in the effective dispersion of lithium ion battery slurry.
