<p>The manufacture of a lithium ion secondary battery which can take optional form such as a thin type, is compact and highly efficient and has stable properties, being composed of a positive electrode (1), a negative electrode (4), a separator (7), and an electrolyte. In this manufacture, a battery laminate, which has layers of laminates (12) each of which is made by laying a positive electrode (1) and a negative electrode (4) severally on a separator (7) after applying the binder resin solution made by dissolving fluoric resin or polyvinyl alcohol in a solvent, to the separator (7) is made, and a plate-shaped battery laminate is made by drying this battery laminate under pressure so as to evaporate the solvent, and then this plate-shaped battery laminate is impregnated with an electrolyte.</p> |
