NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND BATTERY PACK |
| 摘要 |
A nonaqueous electrolyte secondary battery of an embodiment includes an exterior member; a positive electrode housed in the exterior member, a negative electrode containing an active material and housed in the exterior member so as to be spatially separated from the positive electrode via a separator, and a nonaqueous electrolyte filled in the exterior member. The negative electrode includes a negative electrode current collector and a negative electrode active material layer on the negative electrode current collector. A tensile strength of the negative electrode is 400 N/mm2 or more and 1200 N/mm2 or less. A peel strength between the negative electrode current collector and the negative electrode active material layer is 1.5 N/cm or more and 4 N/cm or less. |
