PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary cell having excellent charging and discharging characteristics and cycle life, generating small volume of gas during storage. SOLUTION: For the nonaqueous electrolyte secondary cell with a positive electrode, a negative electrode and a nonaqueous electrolyte dissolving an electrolyte in a nonaqueous solvent, a surfactant shown by the formula (1): X-CNF2N- Y-(CH2-CH2)M-Z, [where; -X is -H or -F, -Y- is -CONH- or -SO2NR- (R is alkali group), -Z is -OH, -CH3, -PO3W2, or -SO3W (W is alkali metal), n is 4-10, m is 20-100], is added to the nonaqueous electrolyte. |
