<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte, reduced in generation of a free acid without management of storage temperature. <P>SOLUTION: The nonaqueous electrolyte includes an aprotic solvent and a lithium salt. The nonaqueous electrolyte contains a stabilizing agent which reacts with the free acid in the nonaqueous electrolyte to suppress the concentration rise of the free acid. The stabilizing agent is composed of an amine-based compound, including at least one selected from cyclooctylamine and amines represented by general formula (R1R2N-X-NR3R4), wherein X is naphtylene group, and R1 to R4 are each independently hydrogen atom, alkyl group or aryl group. <P>COPYRIGHT: (C)2011,JPO&INPIT |
