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 electrolyte solution impregnation time for an electrode active material, setting an optimum estimated electrolyte solution impregnation time of the electrolyte solution for a battery based on a measured result, and reflecting the optimum estimated electrolyte solution impregnation time in a production process.

Claim (Index 1):
A method of preparing a lithium secondary battery, the method comprising steps of:\n forming an electrode material mixture layer having a thickness of 10 \u03bcm to 200 \u03bcm, a porosity of 18 vol % to 30 vol %, and a density of 1 g/cc to 4.5 g/cc by coating a perforated foil with an electrode active material slurry and rolling the coated foil (S1); preparing a non-aqueous electrolyte solution (S2); calculating an electrolyte solution impregnation rate by measuring a time at which the non-aqueous electrolyte solution passes through the electrode material mixture layer (S3); and setting an estimated electrolyte solution impregnation time of a measurement target full cell by using the electrolyte solution impregnation rate (S4).
