摘要：
A nonaqueous electrolyte and a lithium-ion secondary battery using the same, wherein a mixture of a cyclic carbonate, a chain carbonate, a first phosphoric acid ester wherein bonding between carbons is a single bond, and a second phosphoric acid ester wherein bonding between carbons contains a double bond is used as the nonaqueous electrolyte. It is desirable that the first phosphoric acid ester is a trimethyl phosphate. In addition, it is desirable that the second phosphoric acid ester is a dimethylisopropenyl phosphate.
