%X Coating slurries for making anodes and cathodes of
lithium batteries contain a large percentage of solid particles of different
chemicals, sizes and shapes in highly viscous media. A thorough mixing of these
slurries poses a major challenge in the battery manufacturing process. Several
types of mixing devices and mixing methods were examined. The conventional
turbine stirrers or ball mill mixers could be adequately used for the
preparation of anode slurries, but not suitable for cathode slurries. In this
study, a newly three-dimensional mixer, in conjunction with a multi-stage mixing
sequence was proposed. The mixing effectiveness was examined by means of
rheological measurements and flow visualization techniques. Preliminary
electrical performance results indicated that the battery obtained using the 3D
mixing device with a multi-stage mixing sequence was more efficient to those
obtained from conventional methods.
