    • The method for manufacturing a lithium ion secondary battery includes a binder coating step (18), a mixture supplying step (20), a magnetic field applying step (22), and a convection generating step (24). The binder coating step (18) is a step of coating a slurry-form binder (18a) on a metal foil (12a) (collector). The mixture supplying step (20) is a step of supplying a negative electrode mixture containing graphite so as to be superposed on the slurry-form binder (18a) coated on the metal foil (12a) in the binder coating step (18). The magnetic field applying step (22) is a step of applying a magnetic field having magnetic lines of force pointing in the direction orthogonal to the metal foil (12a), to the negative electrode mixture (20a) coated on the metal foil (12a) in the mixture supplying step (20). Further, the convection generating step (24) is a step of generating convection in the negative electrode mixture (20a) by applying heat to the negative electrode mixture (20a) to which a magnetic field has been applied in the magnetic field applying step (22).
    • 锂离子二次电池的制造方法包括粘合剂涂布工序(18),混合物供给工序(20),磁场施加工序(22)和对流生成工序(24)。 粘合剂涂布步骤(18)是在金属箔(12a)(集电体)上涂布浆料形式的粘合剂(18a)的步骤。 混合物供给步骤(20)是在粘合剂涂布步骤(18)中,供给包含石墨的负极混合物以叠加在涂覆在金属箔(12a)上的浆料形式的粘合剂(18a)上的步骤。 磁场施加步骤(22)是将具有与金属箔(12a)正交的方向指向的磁力线的磁场施加到涂覆在金属箔(12a)上的负极混合物(20a)的步骤, 在混合物供给步骤(20)中。 此外,对流生成工序(24)是通过向在磁场施加工序(22)中施加有磁场的负极合剂(20a)进行加热而在负极合剂(20a)中产生对流的工序 )。

    • A coating device is arranged to a strip-shaped base sheet with coating material by holding the coating material on the surface of a coating rod and bringing the base sheet into contact with the coating material held on the coating rod, while conveying the base sheet in the longitudinal direction. The coating rod has a water-repellent section, in which the entire circumferential surface of a part of the rod in the axial direction is coated with a water-repellent material that repels the coating material, and a non-water-repellent section that is not coated with the water-repellent material and arranged adjacent to the water-repellent section. Consequently, even if the base sheet is brought into contact with the coating rod, the base sheet can be adequately provided with an uncoated portion in a part in the width direction since the coating material is repelled in the water-repellent section.
    • 涂布装置通过将涂料保持在涂布杆的表面上并使基材与保持在涂布杆上的涂料接触,同时将基片输送到带状基片上, 纵向。 涂覆杆具有防水部,其中杆的一部分在轴向方向上的整个圆周表面涂覆有排斥涂料的拒水材料,以及非防水部分, 没有涂覆防水材料并邻近防水部分布置。 因此,即使基片与涂布杆接触,由于涂层材料在防水部分中排斥,所以基片可以在宽度方向上的一部分中适当地设置未涂覆部分。
