摘要： A negative electrode, and a method and apparatus for manufacturing a negative electrode, are provided. The apparatus for manufacturing a negative electrode includes a pair of magnet plates including an upper magnet plate and a lower magnet plate respectively disposed above and below a plane (e.g., X-Y plane) in which the negative electrode moves in a direction (e.g., X-axis direction). In the magnet plate, first and second vertical unit magnets and first and second horizontal unit magnets with magnetic force lines having different directions are arranged, and a direction of magnetic force lines of the unit magnets changes by 90 degrees in a second direction (e.g., Y-axis direction) . The upper and lower magnet plates have opposite polarities, and the upper and lower magnet plates have constant magnetic force in the first direction and a magnetic force changing in the second direction.
