| titleOfInvention | Lithium-ion secondary battery |
| abstract | The present invention provides a lithium ion secondary battery capable of obtaining better cycle characteristics even when the charge end voltage is lowered to 4.41V or higher. The invention relates to a lithium-ion secondary battery, which is a winding electrode assembly including a positive electrode with a positive electrode active material layer, a negative electrode with a negative electrode active material layer, and a separator wound into a roll shape, and the charging termination voltage is 4.41V In the winding-type lithium ion secondary battery of the above range and 4.47 V or less, the ratio of the area of the entire negative electrode active material layer to the area of the opposing portion of the positive electrode active material layer and the negative electrode active material layer is 100.5%. More than 104.0%, the gap between the positive electrode and the negative electrode is more than 0.1 mm and less than 0.5 mm in the axial direction of the winding, and the positive electrode active material contained in the positive electrode active material layer per unit weight The discharge capacity is not less than 169.0 mAh/g and not more than 178.0 mAh/g. |
