PROBLEM TO BE SOLVED: To provide a method for manufacturing a positive electrode active material layer for a lithium ion battery, which enables the improvement of a lithium ion battery, especially a lithium ion battery operating on a high voltage in endurance and internal resistance.SOLUTION: A method for manufacturing a positive electrode active material layer for a lithium ion battery according to the present invention comprises the steps of: coating a base with a positive electrode mixture slurry including a positive electrode active material, a first lithium salt, a second lithium salt, and a solvent; and removing the solvent by drying. The first lithium salt is a lithium phosphate; and the second lithium salt is selected from a group consisting of a lithium carbonate, a lithium hydroxide, a lithium nitrate, a lithium acetate, and a lithium sulfate, and combination thereof. The percentage of the second lithium salt to the first lithium salt is 1-50 mol% based on the number of lithium atoms.SELECTED DRAWING: Figure 1 |
