Abstract
A secondary battery manufacturing method injects large amount of electrolyte twice, and reflects the average value of the amount of firstly injected electrolyte into the amount of secondly injected electrolyte to allow electrolyte to be quantitatively injected in a short time. This can reduce the defect rate when manufacturing batteries such as a large-capacity secondary battery or a long cell model secondary battery in which electrolyte 200 g or more is injected, and can also better improve the performance of the secondary battery.
