Beschreibung
Zusammenfassung:	A positive electrode mixture containing: a polyvinylidene fluoride (A); a positive electrode active material (C) represented by the general formula (C): LiyNi1-XMxO2, wherein x is 0.01≤x≤0.7, y is 0.9≤y≤2.0, and M represents a metal atom (excluding Li and Ni); and an additive (D), wherein the polyvinylidene fluoride (A) is a combination of: (A2) a polymer containing vinylidene fluoride unit and a fluorinated monomer unit; and at least one selected from the group consisting of (A3) a polymer containing vinylidene fluoride unit and a polar group-containing monomer unit, and (A4) a polymer containing vinylidene fluoride unit, a fluorinated monomer unit, and a polar group-containing monomer unit. Also disclosed is a positive electrode famed from the positive electrode mixture and a secondary battery including the positive electrode.
