The present invention relates to a method for manufacturing a lithium ion battery, wherein the lithium ion battery has a set of positive electrode current collectors, positive electrode active material layers, separators, negative electrode active material layers and negative electrode current collectors stacked in sequence, and the lithium ion battery The ion battery has a structure in which the outer peripheries of the positive electrode active material layer and the negative electrode active material layer are sealed with a sealing material and an electrolyte solution is sealed, and the method for producing a lithium ion battery is characterized in that the positive electrode and/or the positive electrode and/or the positive electrode are produced through an electrode production process. The process of the negative electrode, the electrode manufacturing process includes a supply process of preparing a frame-shaped sealing material and a bottom surface member, and supplying an electrode active material combination containing electrode active material particles and an electrolyte solution to the space surrounded by the sealing material and the bottom surface member and a compression step of compressing the electrode active material composition to form an electrode active material layer. |
