<P>PROBLEM TO BE SOLVED: To stably obtain superior output characteristics under a low temperature condition even in the case that the amount of a lithium salt having oxalate complex as an anion is changed in a nonaqueous electrolyte secondary battery in which the lithium salt having an oxalate complex as the anion has been added to a nonaqueous electrolytic solution. <P>SOLUTION: In the nonaqueous electrolyte secondary battery provided with a positive electrode 1 and a negative electrode 2 capable of storing and releasing lithium and with the nonaqueous electrolytic solution having lithium ion conductivity in which a solvent is dissolved into a nonaqueous solvent, the lithium salt having the oxalate complex as the anion is added to the nonaqueous electrolytic solution, and fibrous carbon is contained in the positive electrode as a conductive agent. <P>COPYRIGHT: (C)2007,JPO&INPIT |
