    摘要: A nonaqueous electrolyte secondary battery in which the decomposition of an electrolyte solution is reduced exhibits high coulombic efficiency and excellent charge and discharge cycle performance, and has high energy density. This nonaqueous electrolyte secondary battery includes a negative electrode that is formed by depositing a thin film of active material on a collector by a CVD method, sputtering, evaporation, thermal spraying, or plating, wherein the thin film of the active material can lithiate and delithiate and is divided into columns by cracks formed in the thickness direction, and the bottom of each column is adhered to the collector; a positive electrode that can lithiate and delithiate; and a nonaqueous electrolyte solution containing a lithium salt in a nonaqueous solvent. The electrolyte solution contains a compound expressed by a general formula (I). Rn-M=0   (I) (wherein, Rs are alkyl groups optionally having a substituent, may be identical or different from one another, may be independent substituents, or may be bound together to form a ring; M is S or P; and n is 2 when M is S and is 3 when M is P.)
