METHOD OF MANUFACTURING LITHIUM-ION SECONDARY BATTERY |
| 摘要 |
A method of manufacturing a lithium-ion secondary battery proposed herein includes the following steps of: preparing a battery in which an electrode assembly is enclosed in a battery case; filling a first electrolyte solution containing a film forming agent into the battery case; charging and discharging the battery filled with the first electrolyte solution; discharging the first electrolyte solution from the battery that has been charged and discharged; and filling a second electrolyte solution containing a film forming agent at a concentration of less than 0.005 mol/L into the battery case from which the first electrolyte solution has been discharged. |
