Abstract
The method for manufacturing a lithium ion secondary battery includes a binder coating step (), a mixture supplying step (), a magnetic field applying step (), and a convection generating step (). The binder coating step () is a step of coating a slurry-form binder () on a metal foil () (collector). The mixture supplying step () is a step of supplying a negative electrode mixture containing graphite so as to be superposed on the slurry-form binder () coated on the metal foil () in the binder coating step (). The magnetic field applying step () is a step of applying a magnetic field having magnetic lines of force pointing in the direction orthogonal to the metal foil (), to the negative electrode mixture () coated on the metal foil () in the mixture supplying step (). Further, the convection generating step () is a step of generating convection in the negative electrode mixture () by applying heat to the negative electrode mixture () to which a magnetic field has been applied in the magnetic field applying step ().
