<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte capable of excellently inhibiting degradation of a battery, especially reduction in capacity, when used as an electrolyte in a nonaqueous secondary battery. <P>SOLUTION: The nonaqueous electrolyte contains a nonaqueous solvent, and an amide lithium salt as an additive. The amide lithium salt is a derivative of an oxo carbon acid having a valence of 2 or greater or a carboxylic acid having a valence of 2 or greater, and has at least one N-alkane sulfonyl fluoride group. A nonaqueous electrolyte of the composition can excellently inhibit degradation caused by cycles of charge and discharge when used as an electrolyte 90 in a nonaqueous secondary battery 100. <P>COPYRIGHT: (C)2012,JPO&INPIT |
