Non-aqueous electrolytic solutions and batteries comprising non-aqueous electrolytic solutions

摘要

A novel carbonate compound represented by the general formula [I]: R1CH2O-CO-OCH2R2 [I]wherein R1 represents a hydrogen atom, an alkyl group or an alkyl group substituted with one or more halogen atoms, and R2 represents an alkyl group having no hydrogen atom at the alpha -position thereof or an alkyl group substituted with one or more halogen atoms having no hydrogen atom at the alpha -position thereof, with the proviso that R1 is not identical to R2, which has excellent properties as solvent, is disclosed. A non-aqueous electrolytic solution and a battery utilizing the novel carbonate compound are also disclosed.
