Abstract: The present invention provides a battery cell of a plate shape, including: an electrode assembly in which a separator is interposed between a positive electrode and a negative electrode, wherein the electrode assembly may be mounted on a receiving part; and sealing parts formed by heat fusion at an external side of the receiving part, wherein lateral sealing parts adjacent to one of the sealing parts at which an electrode terminal is positioned may closely contact an outer surface of the receiving part while being bent toward the receiving part of a battery case, and a phase change material (PCM) that is phase-changed in response to a thermal change may be added to surplus surfaces of the lateral sealing parts or to surplus spaces between the receiving parts and the bent lateral sealing parts.
