Title: LITHIUM SECONDARY BATTERY PRODUCTION METHOD
Abstract:
The present invention relates to a lithium secondary battery production method which can improve the productivity and performance of a lithium secondary battery by: measuring, with the naked eye, an electrolyte impregnation time for an electrode active material; and setting an expected optimal electrolyte impregnation time for the battery on the basis of the resulting measurement, thereby reflecting the set time in a production process.
