Abstract: A method of manufacturing an electrode composition for lithium-ion batteries that can prevent other electrode materials from forming aggregates on the surface of the coating layer of coated electrode active material particles, and that has good fluidity, and that can suppress deterioration of battery performance, can be provided. The method of manufacturing an electrode composition for lithium-ion batteries, the method including: a first mixing step of obtaining a powder for electrodes by mixing coated electrode active material particles for lithium-ion batteries, in which at least a part of the surface of the electrode active material particles is coated with a polymer compound, with a first conductive filler having an aspect ratio of 10 or less; and a second mixing step of obtaining an electrode composition by mixing the powder for electrodes with a second conductive filler having an aspect ratio of 15 or more.

Abstract: A battery manufacturing method includes forming a unit cell having a positive electrode that is obtained by a positive electrode active material layer containing an electrolytic solution being disposed on a positive electrode current collector, a negative electrode that is obtained by a negative electrode active material layer containing an electrolytic solution being disposed on a negative electrode current collector, and a separator interposed between the positive electrode and the negative electrode. The battery manufacturing method further includes applying pressure to one unit cell or with two or more stacked unit cells from the stacking direction, and charging the one unit cell or the two or more stacked unit cells after applying of the pressure. The method is performed such that the positive electrode and the negative electrode are formed without an application film being subjected to a drying process performed through heating.

Abstract: A manufacturing method is provided for manufacturing an electrode for a lithium-ion battery having a current collector and an electrode active material layer. In the method, an electrolytic solution is added to particles created by pulverizing a mixture containing electrode active material particles and a pressure sensitive adhesive resin to obtain an electrode active material composition. The electrode active material composition is molded into sheet form on a current collector using a roll press. The electrode active material composition has a weight of the electrolytic solution based on a total weight of the electrode active material composition that is 0.1-50 wt %.
