description Disclosed are a mixed positive electrode material, a positive electrode plate and a manufacturing method therefor, and a battery. The mixed positive electrode material comprises: a ternary material and a phase change material; the phase change material has a phase change in a charging/discharging voltage interval of the ternary material; the ternary material has a single-crystal structure, and the phase change material has a single-crystal structure or an aggregate structure; the mass fraction ratio of the ternary material to the phase change material is 70:30 to 99.8:0.2; the nanohardness of the ternary material is 0.001 Gpa to 5 Gpa, and the nanohardness of the phase change material is 0.01 Gpa to 10 Gpa. L'invention concerne un matériau d'électrode positive mixte, une plaque d'électrode positive et son procédé de fabrication, et une batterie. Le matériau d'électrode positive mixte comprend : un matériau ternaire et un matériau à changement de phase; le matériau à changement de phase présente un changement
