摘要： Since it is possible to optionally adjust the used region of a negative electrode, it is possible to obtain a cell having an excellent balance of durability and discharge characteristic, and it is possible to reduce the resistance of a positive electrode. If only the positive electrode is charged before assembling the cell, it is possible to optionally adjust the used region of the negative electrode, so that it is possible to obtain the cell having the excellent balance of durability and discharge characteristic. Also after a large number of charge and discharge cycles are repeated, it is possible to suppress the internal pressure rise of the cell at the last stage of charge. In addition, it is possible to form a good cobalt conductive network on the active material of the positive electrode, and it is possible to reduce the resistance of the positive electrode.
