| 摘要 |
A lithium secondary cell exhibiting excellent long term cell characteristics such as cycle characteristics, electric capacity and storage characteristics, and a nonaqueous electrolyte usable in such a lithium secondary cell. The lithium secondary cell comprising a positive electrode, a negative electrode, and a nonaqueous electrolyte produced by dissolving an electrolytic salt into a nonaqueous solvent is characterized in that the positive electrode is a material containing a lithium composite oxide, the negative electrode is a material containing graphite, and the nonaqueous electrolyte contains a dialkyl oxalate, and a vinylene carbonate and/or 1,3-propane sultone. A nonaqueous electrolyte being employed therein is also provided. |
