The cathode slurry disclosed herein has homogeneous ingredient dispersion and quick drying capability for making a lithium-ion battery with high quality and consistent perfonnance. In addition, these properties of the cathode slurry increase productivity and reduce the cost of manufacturing lithium-ion batteries.
