    摘要： The invention aims to suppress gas generation in a nonaqueous electrolytic cell having a negative electrode containing negative active material such as lithium titanate and particularly suppress swelling in a nonaqueous electrolytic cell by suppressing gas generation at the time of storage at a high temperature. 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/extracted at a potential higher than the lithium potential by 1.2 V. The nonaqueous electrolytic cell is characterized in that the nonaqueous electrolyte contains vinylene carbonate, the negative electrode has a coat thereon, and the nonaqueous electrolytic cell is used in a range of negative electrode potential nobler than the lithium potential by 0.8 V. A nonaqueous electrolytic cell manufacturing method is characterized in that a nonaqueous electrolyte containing vinylene carbonate is used, the initial charge-discharge is carried out under a condition that the negative potential in the completed charged state exceeds the lithium potential by 0.8 V, a coat is formed on the surface of the negative electrode or a coat is formed on the surface of the negative electrode at the initial charge-discharge in such a way at least once, the negative potential is lowered below the lithium potential by 0.4 V.
