PROBLEM TO BE SOLVED: To provide a pouch type secondary battery capable of increasing large thickness and flexibility in outline design, and to provide a method of fabricating the same.SOLUTION: The method for fabricating the pouch type secondary battery includes the following steps of: mounting of an electrode assembly; first sealing; injecting of an electrolyte; and second sealing. In the step of mounting the electrode assembly, an electrode assembly having a first electrode plate attached with a first electrode tab, a second electrode plate attached with a second electrode tab and a separator disposed between the first electrode plate and the second electrode plate is mounted between a first pouch sheet and a second pouch sheet. In the step of first sealing, outer sides of the first and the second pouch sheets are sealed for accommodating the electrode assembly, exposing the first and second electrode tabs outside the assembly, and forming an electrolyte injection passage from the inside to the outside. In the step of injecting the electrolyte, an electrolyte is injected inside the first and the second pouch sheets through the electrolyte injection passage. In the step of second sealing, the electrolyte injection passage is tightly sealed in a state of accommodating the electrode assembly inside of the first and the second pouch sheets. |
