Abstract

Official abstract text for this publication.

A pouch-type lithium secondary battery including: a battery unit comprising a positive electrode plate, a separator, and a negative electrode plate, wherein the separator is disposed between the positive and negative electrode plates; electrode tabs extending from each of the positive and negative electrode plates of the battery unit, respectively; a case having a space to accommodate the battery unit and sealing surfaces formed along the periphery of the space, wherein the case is sealed at the sealing surfaces by thermal fusion; and a protection circuit board 600 electrically connected to the electrode tabs. The protection circuit board is disposed parallel to an outer wall of the case. Since the electrode tabs are bent in an upright position with respect to the sealing surfaces, and the protection circuit board electrically connected to the bent electrode tabs is disposed between the outer wall of the case and the electrode tabs, the size of the sealing surfaces of the case can be minimized.
