US08722243B2 Material for use as electrolyte, lithium secondary battery electrolyte, lithium secondary battery employing the same, and novel lithium salt 有权
用作电解质的材料，锂二次电池电解质，使用其的锂二次电池和新型锂盐

Material for use as electrolyte, lithium secondary battery electrolyte, lithium secondary battery employing the same, and novel lithium salt
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.
