Abstract
A nonaqueous electrolytic cell manufacturing method is characterized in that a nonaqueous electrolyte containing vinylene carbonate is used, a coating on the surface of the negative electrode is formed at the initial charging/discharging in such a way by lowering the negative electrode potential to less than 0.4 V with relative to the lithium potential, wherein the nonaqueous electrolytic cell comprises a nonaqueous electrolyte containing an electrolytic salt and a nonaqueous solvent, a positive electrode, and a negative electrode containing a negative electrode material into/from which lithium ions are inserted/desorbed at a potential higher than the lithium potential by 1.2 V. The nonaqueous electrolytic cell is used in a range of negative electrode potential nobler than the lithium potential by 0.8 V.
