Abstract: A prismatic lithium ion battery having an electrode assembly, a prismatic can which receives the electrode assembly and a cap assembly which closes the open end of the prismatic can, wherein two deformed surfaces are formed in each major surface area of the prismatic can opposite to each other, respectively so that they are bent from exterior to interior and indented, and formed in the shape of a band connecting two narrow sides in the longitudinal direction, and formed one by one close to two large sides of the major surface areas but the intermediate parts are close to each other than the ends. In accordance to the present invention, in case that the expansion of the battery or the internal gas generation, the expansion of the battery in the thickness direction is prevented, and the risk, making an internal short-circuit because the insulating case is not pressed to the can as the prismatic can expand, may be reduced.
