  • Material for use as electrolyte, lithium secondary battery electrolyte, lithium secondary battery employing the same, and novel lithium salt
    Patent number: 8722243
    Abstract: An inventive electrolyte material contains a lithium salt comprising the following components (A1) and (B), or contains the following components (A1), (A2) and (B): (A1) a lithium cation; (A2) an organic cation; and (B) a cyanofluorophosphate anion represented by the following general formula (1): ?P(CN)nF6-n??(1) wherein n is an integer of 1 to 5. The inventive electrolyte material is excellent in electrochemical properties, i.e., has a higher electrical conductivity and a higher oxidation potential, and is capable of forming an electrode protection film, so that a highly safe lithium secondary battery can be provided.
