METHOD FOR PRODUCING ENERGY STORAGE DEVICE AND ENERGY STORAGE DEVICE |
| 摘要 |
A method including: a placing step of placing an electrode assembly including a positive electrode that contains a positive active material and a negative electrode that contains a negative active material, and an electrolyte solution containing an additive in a container; a charging step of charging the electrode assembly placed in the container; and a hermetically sealing step of hermetically sealing the container after the charging step. When starting charging in the charging step, the electrolyte solution contains 1.0 mass % or less of lithium difluoro bis(oxalate)phosphate as the additive. The charge voltage in the charging step is 4.0 V or more. |
