METHOD FOR MANUFACTURING LITHIUM ION SECONDARY BATTERY ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a lithium ion secondary battery electrode, which enables the suppression of formation failure of an active material layer in the case of using granulated powder.SOLUTION: A method for manufacturing a lithium ion secondary battery electrode herein disclosed comprises the steps of: preparing granulated powder including an active material particles and a binder; preparing scale-like graphite; preparing a current collector; supplying a mixture of the granulated powder and the scale-like graphite to the surface of the current collector; and forming an active material layer on the current collector by rolling the mixture of the granulated powder and the scale-like graphite supplied to the surface of the current collector.SELECTED DRAWING: Figure 1
