SLURRY STORAGE DEVICE, SLURRY PRODUCTION SYSTEM AND SLURRY STORAGE METHOD

摘要

To provide a slurry storage device, a slurry production system, and a slurry storage method capable of appropriately storing an aqueous slurry containing a high nickel material among the aqueous slurries.SOLUTION: A slurry storage device, a slurry storage method, and a slurry production system include holding means for holding a slurry containing a high nickel material prepared by a dispersion device, and pH value increase suppressing means that suppresses the increase in a pH value of the aqueous slurry. By providing the pH value increase suppressing means that suppresses the increase in the pH value of the aqueous slurry containing the high nickel material, alkalization of the aqueous slurry held in holding means due to aging can be suppressed, and deterioration of physical property of the slurry can be suppressed. This makes it possible to stably store the aqueous slurry containing the high nickel material for a long period of time.SELECTED DRAWING: Figure 3
