PURPOSE:To obtain a battery having good high load characteristic by winding sheet-shaped positive plate and negative plate around a flat board acting as a core through a separator so as to construct a group of plates. CONSTITUTION:A separator 3 is used after cutting a porous film made of polypropylene, etc., so as to have the width wider than those of a positive plate 1 and a negative plate 2. The plates 1, 2 and the separator 3 are wound around a flat board acting as a core 7 and end of the separator 3, is fixed by an adhesive tape, thereafter the core 7 is pulled out to construct a group of pates having a elliptical cross section. The group of plates are inserted into a battery case 6, lead plates 4 and 5 of the positive and negative poles are spot-welded to the terminal of a sealing plate and no-aqueous electrolyte is poured into the case. Thus, a thin non-aqueous electrolyte battery having excellent high load characteristic and a thin non-aqueous electrolyte secondary battery having a quick charge characteristic are obtained. |
