Cyclic Carbonate-Modified Siloxane Process for Producing the Same Non-Aqueous Electrolytic Solution Secondary Battery and Capacitor

摘要

Cyclic carbonate modified siloxane represented by following formula (1).; Formula 1 ;R ¹_a A _b SiO _{(4-ab) / 2};In formula, R ¹ is the same or heterogeneous selected from a hydroxyl group and a C1-C30 alkyl group which may be substituted by a halogen atom, an aryl group, an aralkyl group, an amino substituted alkyl group, a carboxyl substituted alkyl group, an alkoxy group, an aryloxy group. It is a monovalent group, A is a cyclic carbonate group represented by following formula (2). a and b are positive numbers of 1.0 = a = 2.5 and 0.001 = b = 1.5, respectively, and a + b is 1.001 = a + b = 3. _{^{End, [R 1 ASiO 2/2}} ] The number of units, other than three or less straight chain siloxane and silicon atoms of 3 to 6 cyclic siloxane case.;Formula 2;The battery using the nonaqueous electrolyte containing the cyclic carbonate-modified siloxane of the present invention has excellent temperature characteristics and cycle characteristics.;Cyclic carbonate modified siloxane, nonaqueous electrolyte, secondary battery, capacitor
