Abstract
Disclosed are a battery pack and a method of producing the same. A battery pack includes a cell main body in which a cell element comprising a solid state electrolyte or a gel form electrolyte disposed between a cathode active material layer and an anode active material layer is contained inside a sheath material comprised of an aluminum laminated film, an outer case having a box-like shape with one end face open and containing the cell main body therein, and a cap for closing the open face of the outer case. In the battery pack, initial charging of the cell main body is conducted after the cell main body is contained into the outer case to assemble the battery pack. An enhancement of cell capacity at a fixed outside size or a reduction in outside size at a fixed cell capacity is achieved.

A battery pack comprising a cell main body in which a cell element using a solid state electrolyte or a gel form electrolyte as an electrolyte is contained inside an insulating film form sheath material, a box-shaped outer case with one end face open, and a cap fitted to said open face of said outer case, wherein
- said cell main body is contained in said outer case, and said open face of said outer case is closed with said cap.
A method of producing a battery pack, wherein a cell main body in which a cell element using a solid state electrolyte or a gel form electrolyte as an electrolyte is contained inside an insulating film form sheath material is contained into a box-shaped outer case with one end face open in the condition where initial charging of said cell main body is not yet conducted, and thereafter the initial charging is conducted.
