PROBLEM TO BE SOLVED: To provide an oxide complex by which a nonaqueous lithium ion secondary battery having both of a high discharge capacity and a high discharge rate characteristic can be obtained.SOLUTION: An oxide complex comprises: a lithium-containing complex oxide (A) expressed by the compositional formula (1), LiMnM'O(1) {where M' represents at least one metal element other than Mn or Li; the relation given by 0≤x<1 and 0≤α<1 is satisfied}, and having a lamellar crystal structure with Li arranged in a lamellar form; and an inorganic compound (B) having a relative dielectric constant of 20 or larger.SELECTED DRAWING: None |
