<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte solution for a lithium battery, excellent in safety because a nonaqueous solvent is a nonvolatile (co)polymer, and excellent in ionic conductivity because of high lithium salt solubility, for excellent electric characteristics. <P>SOLUTION: The nonaqueous electrolyte solution for the lithium battery comprises (A): 1 pt.wt. polymer formed by polymerizing carbonate group-containing acrylate monomers represented by general formula (1), (in the formula, R<SB>1</SB>represents a hydrogen atom or a methyl group; R<SB>2</SB>represents a 1-6C alkylene group; R<SB>3</SB>represents a 1-18C hydrocarbon group), containing 0.00 mole or more of carbonate groups per 1 kg of the polymer and having a weight-average molecular weight of 500-10,000; and (B): 1-25 pt.wt. lithium salt. <P>COPYRIGHT: (C)2009,JPO&INPIT |
