| titleOfInvention | Cylindrical secondary battery |
| abstract | The present invention provides a cylindrical secondary battery with improved charge / discharge cycle characteristics accompanied by rapid charge by suppressing variation in the shapes of electrode plates and electrode groups and performing charge / discharge reactions more uniformly. A battery includes a bottomed cylindrical battery case having an opening, an electrode group accommodated in the battery case, a non-aqueous electrolyte having lithium ion conductivity, and a sealing member closing the opening of the battery case. Equipped with The electrode group includes a positive electrode, a negative electrode 12, and a separator interposed between the positive electrode and the negative electrode, and the positive electrode and the negative electrode are formed by winding through the separator. . The negative electrode includes a negative electrode current collector 121 and a negative electrode active material layer 122 held on at least one main surface of the negative electrode current collector, and the negative electrode current collector does not hold the negative electrode active material layer. It has an exposed part. The ratio (= A / S) of the total area A of the exposed portion to the total area S of both main surfaces of the negative electrode current collector satisfies 0.1 ≦ A / S ≦ 0.5.
