Abstract

The present invention provides a method of manufacturing n battery cells (n≥2), each including a respective reference electrode for measuring a relative electrode potential, including: (i) manufacturing a reference cell composed of an electrolyte solution, the reference electrodes, and a lithium electrode; (ii) charging the reference cell; (iii) charging the reference cell to 40% to 60% of a capacity discharged in the process (ii), thereby performing formation on the reference electrodes; (iv) manufacturing the n battery cells, each of the battery cells including a respective one of the reference electrodes, an electrode assembly, the electrolyte solution and a battery case; and (v) in each of the battery cells, measuring a relative potential of the respective one of the reference electrodes and a positive electrode of the respective electrode assembly, and a relative potential of the respective one of the reference electrodes and a negative electrode of the respective electrode assembly.
