Abstract
A method for manufacturing unit cells includes preparing a pre-cell having a first separator sheet and a plurality of first electrodes disposed on the first separator sheet while being spaced apart from one another; forming a cutting guide line having a plurality of though-holes spaced apart from one another on the pre-cell; and cutting the pre-cell along the cutting guide line to form a plurality of unit cells. An apparatus for manufacturing unit cells includes a hole-forming unit configured to form a cutting guide line on a pre-cell having a separator sheet and electrodes disposed on the separator sheet where the cutting guide line has a plurality of though-holes spaced apart from one another; and a cutting unit configured to cut the pre-cell along the cutting guide line to form a plurality of unit cells.
