METHOD FOR PRODUCING LITHIUM ION CELL ACTIVE MATERIAL PARTICLES

摘要

[Problem] To continuously produce lithium ion cell active material particles having small (nanometer-order) particle diameters and high crystallinity. [Solution] A method for producing lithium ion cell active material particles, characterized by having the step of: causing a plurality of raw material solutions to flow through a raw material-supplying channel under a pressure of 0.3-500 MPa, the plurality of raw material solutions being capable of generating lithium ion cell active material particles or lithium ion cell active material precursor particles when a chemical reaction is induced by mixing; and causing the plurality of raw material solutions to mix at the point where the raw material-supplying flow paths converge so that the lithium ion cell active material particles are continuously generated from the chemical reactions or the lithium ion cell active material precursor particles are continuously generated from the chemical reactions.
