で被つたことを特徴とする渦巻形電池。 In a spiral battery whose capacity is regulated by the porosity or pore volume of the carbon electrode, the carbon electrode is used as the positive electrode and the positive and negative electrode active materials are in excess, and the carbon positive electrode is wound on the inside and the negative electrode is wound on the outside. Furthermore, the spiral battery is characterized in that the outermost periphery of the electrode group is covered with a carbon electrode current collector.
