摘要:
A nonaqueous electrolyte secondary battery includes a positive electrode having a positive electrode active material layer provided on a positive electrode collector, a negative electrode having a negative electrode active material layer provided on a negative electrode collector, and a nonaqueous electrolyte. The nonaqueous electrolyte contains at least one member selected from the group consisting of sulfone compounds represented by the following formulae (1) and (2); and an inorganic phosphorus compound represented by the following formula (3) exists on the surface of a positive electrode active material: R1 represents CmH2m-n1Xn2; X represents a halogen; m represents an integer of from 2 to 7; each of n1 and n2 independently represents an integer of from 0 to 2m; R2 represents CjH2j-k1Zk2; Z represents a halogen; j represents an integer of from 2 to 7; each of k1 and k2 independently represents an integer of from 0 to 2j; each of R3, R4 and R5 independently represents H or OH; and a is 0 or 1.
