Abstract
The present invention relates to a method of preparing a lithium secondary battery which may improve productivity and performance of the lithium secondary battery by visually measuring an actual electrolyte solution impregnation time for an electrode active material, setting an estimated impregnation time of the electrolyte solution for a battery based on a measured result, and reflecting the estimated impregnation time in a production process.
