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.

The present application relates to an optical film and a method for producing a polarizing plate. The present application can provide an optical film satisfying optical and mechanical durability required in a polarizing plate effectively and capable of forming a polarizing plate without causing bending when applied to a display device, and a method for producing a polarizing plate to which the optical film is applied. The present application can provide an optical film capable of realizing the required optical and mechanical durability without causing bending even in a polarizing plate applied to a thin display device and/or a thin polarizing plate, and a method for producing a polarizing plate to which the optical film is applied.
