1. An apparatus for preparing a cell, the apparatus comprising:
a first electrode reel from which a first electrode sheet is unwound, wherein the first electrode sheet is configured to form a plurality of first electrodes;
a second electrode reel from which a second electrode sheet is unwound, wherein the second electrode sheet is configured to form a plurality of second electrodes;
a separator reel from which a separator sheet is unwound, wherein the separator sheet is configured to be stacked with the plurality of first and second electrodes while covering an electrode of the plurality of first and second electrodes by being folded when the respective electrode of the plurality of first and second electrodes is stably placed;
a table having an upper surface on which the plurality of first and second electrodes and the separator sheet are stably placed;
a first nozzle configured to apply an adhesive to at least a portion of a first region of the separator sheet which covers a second electrode of the plurality of second electrodes; and
a second nozzle configured to apply the adhesive to at least a portion of a second region of the separator sheet which covers a first electrode of the plurality of first electrodes,
wherein the table is configured to repeatedly move between a first position and a second position spaced apart from one another along a horizontal dimension, and the first and second nozzles are positioned above the table along a vertical dimension transverse to the horizontal dimension,
wherein the first nozzle is configured to apply the adhesive to the portion of the first region of the separator sheet positioned underneath the first nozzle in the vertical dimension, and
wherein the second nozzle is configured to apply the adhesive to the portion of the second region of the separator sheet positioned underneath the second nozzle in the vertical dimension.
