<P>PROBLEM TO BE SOLVED: To provide a non-aqueous electrolytic solution secondary battery to meet a high input-output characteristic and a satisfactory heat cycle characteristic and, a non-aqueous electrolytic solution used for the battery. <P>SOLUTION: The non-aqueous electrolytic solution secondary battery comprises a positive pole, a negative pole containing a material capable of occluding and discharging lithium, and a non-aqueous electrolytic solution which contains a non-aqueous solvent and lithium salt. The non-aqueous electrolytic solution has a characteristic that it contains silicide which is expressed by a formula: SiF<SB>x</SB>R<SP>1</SP><SB>l</SB>R<SP>2</SP><SB>m</SB>R<SP>3</SP><SB>n</SB>(R<SP>1</SP>-R<SP>3</SP>are organic radicals with the carbon number 1-12, which may either be the same or different. The x denotes 1-3 and the l, m and n denote 0-3 with 1≤l+m+n≤3). <P>COPYRIGHT: (C)2004,JPO |
