| Zusammenfassung: | A nonaqueous electrolyte lithium secondary cell comprising a positive electrode ( 1 ), a negative electrode ( 2 ) and a nonaqueous electrolyte containing a lithium salt is characterized by that the nonaqueous electrolyte contains a room temperature molten salt as a main component, a material wherein a working potential of the negative electrode ( 2 ) is nobler by above 1V than a potential of a metallic lithium is used for a negative active material of the negative electrode. This nonaqueous electrolyte lithium secondary cell has excellent safety and cell performance. |
