<P>PROBLEM TO BE SOLVED: To provide a pouch type lithium secondary battery and its manufacturing method with manufacturing processes curtailed and an impregnating property of electrolyte solution improved. <P>SOLUTION: The pouch type lithium secondary battery forms a second groove 320 in which an electrode assembly is housed at one side of a multilayer film pouch 300c making up a bottom plate of the case and a first groove 310 to be a gas room at the opposite side of the multilayer film pouch 300c making up a top plate, so that the first groove 310 is superposed on the second groove 320 as the multilayer film pouch 300c is folded. <P>COPYRIGHT: (C)2007,JPO&INPIT |
