Unit cell preparation apparatus and method

An apparatus for preparing a unit cell, the apparatus comprising:

• a center electrode reel from which a center electrode sheet is unwound, wherein the center electrode sheet is configured to form a plurality of center electrodes;
• separator reels from which separator sheets to be stacked with the center electrodes are unwound;
• a laminator including a heating roller and a heater configured to apply heat and pressure to laminate a stack which is formed by stacking the plurality of center electrodes with the separator sheets while the plurality of center electrodes are spaced apart from each other and disposed in a row in a longitudinal direction of the separator sheets;
• a first nozzle configured to apply an adhesive to an upper surface of a separator sheet disposed on an uppermost layer of the laminated stack;
• and
• an upper electrode reel from which an upper electrode sheet is unwound, wherein the upper electrode sheet is configured to form a plurality of upper electrodes configured to be stacked on an upper surface of the laminated stack to which the adhesive has been applied,
• wherein the heat and pressure applied by the heating roller is greater than the heat and pressure applied by the heater.
