PROBLEM TO BE SOLVED: To improve a filling rate, capacity, and a cycle characteristic by using a conductive material, different from that of the other surface, to one surface of at least one electrode seat out of positive and negative battery seats. SOLUTION: Conductive material, containing carbon material, a transition metallic compound, and binding material is coated on one surface of a current collecting body to obtain a positive electrode sheet, and also the conductive material, containing carbonaceous material, is coated on one surface of a current collector to obtain a negative electrode sheet. And conductive material, having a different mean particle diameter, is coated on the other side surface of at least one electrode sheet of these positive and negative electrode sheets. |
