Abstract:
A method of manufacturing a nonaqueous-electrolyte secondary battery, the method comprising the steps of:covering a laminating structure with a package member, the laminating structure comprising a positive electrode and a negative electrode, the package member having a sealing member inserted between a lead electrode whose one end connects to the laminating structure and the other end of the lead electrode protrudes from an end of the package member toward an outside of the package member; and fusing the sealing member by: applying pressure with a heater to at least the end of the package member from the outside, and wherein a stripping sheet, which has a sheet-like shape made of a material such that its surface does not fuse and adhere to the sealing member, is inserted between the heater and the package member or the sealing member, the application of the pressure forming the package member into a flat shape; separating the stripping sheet from the package member or the sealing member, whereby after the sealing member can spread between the lead electrode and the package member without a gap by fusing the sealing member, the stripping sheet is separated from the heater; and re-solidifying the sealing member to a solid state.
