More Information
Summary:Disclosed is a nonaqueous secondary battery having a nonaqueous electrolyte containing a lithium salt dissolved in an organic solvent, in which the positive electrode active material is preferably a manganese-containing, lithium transition metal oxide salt. The nonaqueous electrolyte contains at least one compound of general formula (1), preferably at least one compound of general formula (1′). The content of the compound of formula (1) or (1′) in the nonaqueous electrolyte is preferably 0.001 to 10 mass %. The symbols in formulae (1) and (1′) are as defined in the description.
