Abstract
A battery cell with an electrode assembly and a pouch case is disclosed herein. The electrode assembly can include a positive electrode, a negative electrode, and a separator interposed therebetween. The electrode assembly can have a planar shape with four sides. The pouch case can accommodate the electrode assembly. The pouch case can include a first accommodating portion to accommodate a portion of the electrode assembly, a second accommodating portion to accommodate the remaining portion of the electrode assembly. A folding portion of the pouch case can be configured to fold the pouch case such that the first accommodating portion and the second accommodating portion face each other. The pouch case can include a seam allowance formed by boning an extension of a sealing portion of the pouch case to an extension of the folding portion at an intersection of the folding portion and the sealing portion.
