Abstract
Official abstract text for this publication.
Provided is a carbonate-containing silane compound having a characteristic structure that at least two silicon atoms are linked by a carbon chain. The silane compound is chemically stable. When used as an additive to a nonaqueous electrolyte solution, the silane compound does not jeopardize the safety of lithium ion secondary batteries.
First claim
Opening claim text (preview).
The invention claimed is: 1. A carbonate-containing silane compound having the general formula (1): wherein R 1 and R 4 are each independently a substituted or unsubstituted C 1 -C 10 straight or branched divalent hydrocarbon group, R 2 , R 3 , R 5 , R 6 and R 7 are each independently a substituted or unsubstituted C 1 -C 10 straight or branched alkyl or alkenyl group, R 8 is an unsubstituted C 1 -C 10 monovalent hydrocarbon group, and n is 1 or 2, wherein at least one of R 2 , R 3 , R 5 , R 6 and R 7 is a substituted or unsubstituted C 2 -C 10 straight or branched alkenyl group. 2. A method for preparing the carbonate-containing silane compound of claim 1 , comprising the step of effecting condensation reaction of a silyl alcohol compound having the general formula (2): wherein R 1 to R 7 and n are as defined above, with a halogenated formate having the general formula (3): wherein R 8 is as defined above and X is halogen in the presence of a base. 3. The method of claim 2 wherein the base is a heterocyclic amine or tertiary amine.
