<p>The present invention relates to a method and a system for manufacturing a uniformized cell. The present invention provides a method for manufacturing a uniformized cell comprising the steps of: (1) maintaining the constant voltage of a discharged cell; and (2) evaluating whether or not the cell in an open circuit state satisfies the undermentioned mathematical formula at the time of T_1, wherein T_1 is 5 minutes to 2 hours and, if the undermentioned mathematical formula is not satisfied, step (1) and step (2) are repeated. According to the present invention, the performance of a cell can be maintained consistently and uniformly. The mathematical formula is: aOCV_1<= OCV_2<= bOCV_1, wherein OCV_1 is target OCV, OCV_2 is OCV measured at the time of T_1, and a and b are margins of error respectively.</p> |
