1. An apparatus for manufacturing a battery cell by stacking a negative electrode, a separator, and a positive electrode, the apparatus comprising:
a loading unit configured to load the negative electrode, the separator, and the positive electrode;
a negative electrode stacking unit disposed in a first direction of the loading unit, and configured to cut a negative electrode material unwound from a negative electrode roll to a preset first length and to stack the cut negative electrode material on the loading unit;
a separator stacking unit disposed in a second direction of the loading unit, and configured to cut a separator material unwound from a separator roll to a preset second length and to stack the cut separator material on the loading unit; and
a positive electrode stacking unit disposed in a third direction of the loading unit, and configured to cut a positive electrode material unwound from a positive electrode roll to a preset third length and to stack the cut positive electrode material on the loading unit,
wherein the cut negative electrode material, the cut separator material, and the cut positive electrode material are sequentially staked on the loading unit,
wherein the negative electrode material is cut while being fixed to the negative electrode stacking unit through vacuum adsorption, the cut negative electrode material is transferred to the loading unit without losing vacuum adsorption, and the cut negative electrode material remains fixed in the loading unit through vacuum adsorption,
wherein the separator material is cut while being fixed to the separator stacking unit through vacuum adsorption, the cut separator material is transferred to the loading unit without losing vacuum adsorption, and the cut separator material is stacked on the cut negative electrode material while the cut negative electrode material is fixed to the loading unit through vacuum adsorption, and
wherein the positive electrode material is cut while being fixed to the positive electrode stacking unit through vacuum adsorption, the cut positive electrode material is transferred to the loading unit without losing vacuum adsorption, and the cut positive electrode material is stacked on the cut separator material while the cut separator material is stacked on the cut negative electrode material.
