Disclosed is a secondary battery configured to have a structure in which an electrode assembly is accommodated together with an electrolyte material in a battery case, wherein a space for accommodating the electrode assembly is provided in the battery case, and wherein the battery case Made of injection moldable thermoplastic resin. In the case of using a secondary battery having a space for an electrode assembly and an electrolyte material and including a battery case made of an injection moldable thermoplastic resin, an injection mold may be formed such that the size of the mold corresponds to the thickness of the electrode, Thus, the problem of low formability of conventional laminates including metal layers is solved. In addition, the process of forming the laminated sheet and the process of sealing the battery case with the pressing member, which is necessarily required in order to use the laminated sheet, can be omitted, thereby simplifying the manufacturing process and thereby improving the productivity. |
