Abstract
An object is to provide a process for producing a compact lithium ion secondary battery which exhibits high and stable performance and can take an arbitrary shape such as a thin shape. A process for producing a battery comprised of a positive electrode (,), a negative electrode (,), a separator (,) and an electrolytic solution comprises applying a binder resin solution mainly comprising a fluorocarbon resin or polyvinyl alcohol to a separator (,), laying a positive electrode (,) and a negative electrode (,) alternately on the separator (,) to form a laminated battery body having a plurality of laminates (,), drying the laminated battery body under pressure to form a tabular laminated battery body, and impregnating the tabular laminated battery body with an electrolytic solution.
