The invention discloses a
slurry-homogenizing process for positive
electrode slurry of a
lithium ion battery, a positive
electrode plate and the
lithium ion battery, and belongs to the technical field of manufacturing of the
lithium ion battery. The
slurry-homogenizing process for the positive
electrode slurry of the
lithium ion battery comprises the steps of preparing an
adhesive solution, stirring by a V-shaped stirrer, performing pre-mixing and stirring, performing high-speed stirring, performing
viscosity adjustment, performing vacuum defoaming and the like; the positive electrode plate of the
lithium ion battery comprises a positive electrode
current collector and the positive electrode slurry for
coating the positive electrode
current collector; the positive electrode
current collector adopts an
aluminum foil; the positive electrode slurry is prepared by the slurry-homogenizing process for the positive electrode slurry of the
lithium ion battery; and the lithium ion battery adopts the positive electrode plate of the lithium ion battery prepared by the method. By adoption of the slurry-homogenizing process, the
solid content of the slurry is increased, so that
solid granule friction in stirring can be improved, and the uniformity and the stability of the slurry can be improved; and by lowering a baking temperature in a
drying oven in
coating and
drying, gaps formed between active material granules, conducive carbon granules and a binder can be reduced, thereby enhancing an
adhesive effect and improving the performance of the lithium ion battery.
