Abstract: An electrode for a non-aqueous electrolyte secondary battery, includes a current collector; a first electrode active material layer including a first electrode active material, arranged on a surface of the current collector; and a second electrode active material layer including a second electrode active material, arranged on a surface of the first electrode active material layer. The first electrode active material layer includes a binder in a crystallized state, and the second electrode active material layer does not include a binder. A thickness of the second electrode active material layer is 150 ?m or more, and a total of a thickness of the first electrode active material layer and the thickness of the second electrode active material layer is 250 ?m or more. A ratio of the thickness of the first electrode active material layer to the thickness of the second electrode active material layer is 0.108 or less.

Abstract: To provide an electrode for a non-aqueous electrolyte secondary battery which retains the shape while retaining a discharge capacity at a high rate. An electrode for a non-aqueous electrolyte secondary battery has a current collector and an electrode active material layer arranged on a surface of the current collector, and is used for a non-aqueous electrolyte secondary battery having a liquid volume coefficient of 1.4 to 2.0, in which the electrode active material layer includes an electrode active material and a binder including polyvinylidene fluoride (PVdF), and the polyvinylidene fluoride (PVdF) is in a non-crystallized state and is included in the range of 0.5 to 3.3% by volume with respect to the total volume of the electrode in the electrode active material layer.

An electrode for a non-aqueous electrolyte secondary battery includes a current collector, a first electrode active material layer including a first electrode active material, arranged on a surface of the current collector, and a second electrode active material layer including a second electrode active material, arranged on a surface of the first electrode active material layer, in which the first electrode active material layer includes a binder in a crystallized state and the second electrode active material layer does not substantially include a binder in a crystallized state.

Abstract: To provide a means capable of suppressing the generation of cracks in an electrode active material layer in the production of an electrode for a non-aqueous electrolyte secondary battery. Provided is a method for producing an electrode for use in a non-aqueous electrolyte secondary battery, including a current collector and an electrode active material layer including an electrode active material, arranged on a surface of the current collector, and a dispersion is by mixing the electrode active material, a binder formed of polyvinylidene fluoride (PVdF), a first solvent in which the polyvinylidene fluoride (PVdF) is not dissolved, and a second solvent in which the polyvinylidene fluoride (PVdF) can be dissolved. Then, an electrode active material slurry is prepared by removing the second solvent from the obtained dispersion. Then, a coating film is formed by coating the obtained electrode active material slurry on the surface of the current collector, thereby producing an electrode.
