Abstract
To provide a process for producing a lithium ion secondary battery which can have any arbitrary shape, such as thin shape, and yet exhibits high performance. In a method of fabricating a battery comprising a positive electrode 1, a negative electrode 4, and a separator 7, a binder resin solution mainly comprising polyvinylidene fluoride is applied to the separator 7, and the positive electrode 1 and the negative electrode 4 are laid thereon, followed by drying to form a battery laminate, which is then impregnated with an electrolytic solution.
