NONAQUEOUS ELECTROLYTE SECONDARY CELL AND METHOD FOR USING SAME

摘要

The invention is to provide a nonaqueous electrolytic solution secondary battery capable of preventing gas generating during high-temperature storage and having good battery characteristics. The present invention relates to a nonaqueous electrolytic solution secondary battery comprising: a nonaqueous electrolytic solution that contains a lithium salt and a nonaqueous solvent to dissolve the lithium salt; a negative electrode capable of occluding and releasing a lithium ion; and a positive electrode, wherein the negative electrode contains a negative electrode active material that occludes and releases a lithium ion at a potential nobler than 1.0 V (vs. Li/Li + ), the nonaqueous solvent contains diethyl carbonate, and the nonaqueous electrolytic solution further contains an acid anhydride.
