ABSTRACT:
An object of the present invention is to provide a rectangular or sheet-like cell being capable of supplying the flow of a large current, and having a large energy density per volume, at least comprising a negative electrode active material, a separator, a positive electrode active material, an electrolyte, and a collector, characterized in that positive electrodes made of positive electrode active material and negative electrodes made of negative electrode active material are formed in a plurality of regions separated from each other at least on a foldable insulating member, and the cell is housed being folded up in a resin having no active material. According to the present invention, a rectangular cell can be fabricated which can attain an energy density equivalent to that of spirally wound cylindrical cell, and supply the flow of a large current, with the dead space of cell storage space reduced to the utmost. Further, since the integration can be effected even with a single cell, a sheet-type or rectangular cell having a higher cell voltage can be made. Also, the manufacturing process of cells can be simplified.
