The thin battery of the invention comprises an anode material, a cathode material, two or more separator paper layers there between, and electrolyte. One of the outer separator paper layers has an anode material applied thereon, another separator paper layer being an outer layer on the opposite side having a cathode material applied thereon. The method of the invention for manufacturing such a thin battery is mainly characterized by the steps of wetting a separator paper with an electrolyte solution, applying an anode material on a first separator paper and applying a cathode material on a second separator paper. The separator papers are then combined by pressing them together so that the anode and cathode materials are outmost, respectively in order to form a layered structure. The combined layers are then cut in desired sizes.
A thin battery having a layered structure, comprising an anode material layer, a cathode material layer, two or more separator paper layers there between, and electrolyte solution, wherein one of the outer separator paper layers has the anode material coated or printed thereon as a paste, and another separator paper layer being an other outer layer on the opposite side having the cathode material coated or printed thereon as a paste.
Method of manufacturing a thin battery having a layered structure comprising an anode material layer, a cathode material layer, two or more separator paper layers there between, and electrolyte, the method comprising the steps of:
