<P>PROBLEM TO BE SOLVED: To obtain a non-aqueous electrolyte secondary battery using a negative electrode active material having at least one kind selected from a group of Si atom, Sn atom, and Pb atom which has a high charging capacity and an excellent characteristics for a long period, and which is superior, in particular, in discharge capacity maintenance rate. <P>SOLUTION: A carbonate having at least one of an unsaturated bonding and a halogen atom and a compound as expressed by a general formula (1) are at least contained in the non-aqueous electrolytic solution. In the formula, R<SP>1</SP>and R<SP>2</SP>express respectively and independently a hydrocarbon group which may have a substitution group and have carbon number of 15 or less. R<SP>1</SP>and R<SP>2</SP>may form an annular structure by mutually bonding with each other. <P>COPYRIGHT: (C)2008,JPO&INPIT |
