Abstract
A non-aqueous electrolytic solution for use in a lithium secondary battery has reduced or eliminated flammability and increased capacity retention. The electrolytic solution includes a lithium salt, a carbonate, a substituted phosphazene, a fluorinated solvent such as fluorinated carbonate, fluorinated ether, and fluorinated ester, and an organic phosphate or organic phosphonate such as fluorinated alkyl phosphate, fluorinated aromatic phosphate, fluorinated alkyl phosphonate, or fluorinated aromatic phosphonate.
