Method for producing positive electrode for lithium ion secondary battery and positive electrode for lithium ion secondary battery |
| abstract |
An object of the present invention is to suppress an increase in reaction resistance when producing a positive electrode containing LiMn composite oxide particles using an aqueous solvent. (A) LiMn composite oxide particles are prepared. (B) The coated particles are prepared by forming a film containing Li + conductive oxide on the surface of the LiMn composite oxide particles. (C) Fluorine is introduced into at least a part of the coated particles. (D) A fluid composition is prepared by mixing coated particles in which fluorine is introduced at least in part, a conductive material, an aqueous binder, and an aqueous solvent. (E) A positive electrode mixture layer is formed by disposing the fluid composition on the surface of the current collector. (F) A positive electrode for a lithium ion secondary battery is produced by drying the positive electrode mixture layer. The coating is formed to have a thickness of 5 nm to 10 nm. In the coated particles, fluorine is introduced so that the ratio of the number of fluorine atoms to the number of manganese atoms is 1.95 or more and 3.1 or less. [Selection] Figure 1 |
