<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 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 1 pt.wt. copolymers formed by copolymerizing 55-95 wt.% carbonate group-containing acrylates and 5-45 wt.% vinylene carbonates containing 0.002 mole or more of carbonate groups per 1 kg of copolymer and having a weight-average molecular weight of 500-10,000, and 1-25 pt.wt. lithium salt. <P>COPYRIGHT: (C)2009,JPO&INPIT |
