PRODUCTION METHOD OF REACTIVE AGGLOMERATED PARTICLE, PRODUCTION METHOD OF CATHODE ACTIVE SUBSTANCE FOR LITHIUM-ION BATTERY, PRODUCTION METHOD OF LITHIUM-ION BATTERY, AND PRODUCTION APPARATUS OF REACTIVE AGGLOMERATED PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a production method in which a metallic agglomerated particle, that is expected to have high performance as a cathode active substance and has small particle size and a narrow particle size distribution, can be mass-produced in a small-sized facility.SOLUTION: A whirling current is generated in a reaction processor 10 as a liquid current and additional liquids A, B, each of which contains an inorganic substance to be added, are injected in a reaction field in the reaction processor 10 at the center position parted from the inside surface of the reaction processor 10 to perform reaction processing. The liquid in the reaction processor is circulated and a return liquid of the circulation liquid is injected into the reaction processor to generate the whirling current.
