Abstract
A lithium secondary battery including a positive electrode including a positive electrode material mixture containing a positive electrode additive, a negative electrode, a separator, and an electrolyte. The positive electrode additive includes at least one selected from the group consisting of a first compound represented by formula (1): LiFeM1Oand a second compound represented by formula (2): LiNiM2O. The formula (1) satisfies 0≤a1≤5, 0≤x1≤5, 0≤y1≤1, and 0≤z1≤4, where at least two of a1, x1, y1 and z1 are greater than 0. The formula (2) satisfies 0≤a2≤2, 0≤x2≤1, 0≤y2≤1, and 1≤z2≤2, where at least one of a2 and x2 is greater than 0. The electrolyte contains an oxalate complex salt having an oxalate complex anion and a lithium ion.
