Apparatus and method for manufacturing negative electrode

An apparatus for manufacturing a negative electrode, the apparatus comprising:

• a pair of magnet plates including an upper magnet plate and a lower magnet plate disposed above and below an X-Y plane along which a negative electrode is moved in an X-axis direction in manufacturing the negative electrode,
• wherein each of the magnet plates includes (N+1) magnet modules including a plurality of first vertical unit magnets having a magnetic force direction directed in a positive Z-axis direction, a plurality of second vertical unit magnets having a magnetic force direction directed in a negative Z-axis direction, a plurality of first horizontal unit magnets having a magnetic force direction directed in a negative Y-axis direction, and a plurality of second horizontal unit magnets having magnetic force direction directed in a positive Y-axis direction, wherein the first and second vertical unit magnets and first and second horizontal unit magnets are arranged in a predetermined pattern in a Y-axis direction, where N is an integer equal to or greater than 1,
• wherein the magnet modules are arranged in an X-axis direction parallel to the X-Y plane,
• wherein, when a Y-coordinate of a first unit magnet of a first magnet module, among the magnet modules, is 0, an absolute value of a Y-coordinate of a first unit magnet of an (N+1)th magnet module is N×d, and
• wherein the first unit magnet of the (N+1)th magnet module have an identical type to a first unit magnet of an Nth magnet module, and is offset in the Y-axis direction by a distance (d) smaller than a width of the unit magnet in the Y-axis direction, from a linear line parallel to an X-axis direction passing through an origin point (ON) of the Nth magnet module.
