<P>PROBLEM TO BE SOLVED: To provide a battery to enable improvement in discharge characteristics at a low temperature, improvement in discharge characteristics under a high output, and improvement in safety, to provide an electrochemical capacitor such as an electric double layer capacitor, to provide a nonaqueous electrolytic solution to obtain a nonaqueous electrolytic solution secondary battery in particular, and to provide an electric storage device (battery, capacitor) using this. <P>SOLUTION: This nonaqueous electrolytic solution has essential components of a nonaqueous solvent, an electrolyte salt, and a polyoxyalkylene modified silane expressed by a formula (1): R<SP>1</SP><SB>(4-x)</SB>-Si-A<SB>x</SB>. In the formula (1), R<SP>1</SP>is the same or a different kind of an organic group selected from a halogen substitutible C<SB>1-30</SB>alkyl group, an aryl group, an aminosubstituted alkyl group, a carboxyl substituted alkyl group, an alkoxy group, and an aryloxy group, x is an integer of 1 to 4, and A is a polyoxy alkylane group of a formula (2): -R<SP>2</SP>0-(C<SB>a</SB>H<SB>2a</SB>O)<SB>b</SB>-R<SP>3</SP>(R<SP>2</SP>is a bivalent organic group of C<SB>2-20</SB>which may contain an ether bond or an ester bond, a is an integer of 2 to 4, b is an integer of 1 to 6, R<SP>3</SP>is a group selected from a halogen substitutible C<SB>1-30</SB>alkyl group, an aryl group, an aralkyl group, an amino substituted alkyl group, and an carboxyl substituted alkyl group). The electric storage device using the nonaqueous electrolytic solution containing the polyoxy alkylane modified silane has superior temperature characteristics and high output characteristics. <P>COPYRIGHT: (C)2007,JPO&INPIT |
