Method for manufacturing secondary battery |
| abstract |
The present invention relates to a method for manufacturing a secondary battery comprising: a formation step for charging an assembled secondary battery to an SOC of 45% to 65%; an aging step for aging the secondary battery for which the formation has been completed; and a low voltage testing step for measuring the change in voltage value, wherein, in the low voltage testing step, a voltage value is measured in an SOC interval of 30% or lower. Since an SEI coating is stably formed in the method for manufacturing a secondary battery of the present invention, charging time is shortened and thus the secondary battery can be mass-produced. In addition, since a low voltage test is performed in an interval in which the voltage change rate per capacity of a negative electrode is high, a low voltage defect due to non-uniformity of the formation process can be detected in the method for manufacturing the secondary battery of the present invention. |
