The present invention relates to a method of manufacturing a reference cell comprising the steps of (i) preparing a reference cell composed of an electrolytic solution, n (n? 2) reference electrodes, and a lithium electrode; (ii) performing a discharge immediately after the reference cell is charged by applying a minute current to the reference cell; (iii) forming reference electrodes simultaneously at a flat potential by charging reference cells by 40% to 60% of the discharged capacity in the process (ii); (iv) fabricating each of the prepared reference electrodes and n battery cells with an electrode assembly, an electrolyte, and a battery case; And (v) measuring relative potentials of the formed reference electrode and the anode, and a relative potential of the reference electrode and the cathode, in each of the battery cells, and a method of manufacturing the battery cell, to provide. |
