Abstract

The present application provides a positive electrode plate, a method for preparing the same, and a battery. The positive electrode plate includes a positive current collector, a first positive electrode active coating layer, and a second positive electrode active coating layer. In the first positive electrode active coating layer, a mass ratio of a first lithium manganese iron phosphate active material to a nickel-cobalt-manganese ternary active material is (80-90):(8-15). The second positive electrode active coating layer includes a second lithium manganese iron phosphate active material. An areal density ρ₁ of the first positive electrode active coating layer and an areal density ρ₂ of the second positive electrode active coating layer satisfy: ρ₁ ≥ 240 g/m², ρ₂ ≥ 240 g/m², and |ρ1 - ρ2| ≤ 5 g/m².
