Abstract
A positive electrode material includes a first lithium manganese iron phosphate material in an aggregate form, a second and third lithium manganese iron phosphate materials in an aggregate and/or single-crystal-like form, and a fourth and fifth lithium manganese iron phosphate materials in a single-crystal-like form. A particle quantity ratio of the first to fifth lithium manganese iron phosphate materials is (0.8 to 1.2):(0.8 to 1.2):(1.6 to 2.4):(6.4 to 9.6):(6.4 to 9.6), and particle size Drelationships satisfy: D<D<D<D<D, D=aD, D=bD, D=cD, D=dD, and 5 μm≤D≤15 μm, where 0.35≤a≤0.5, 0.2≤b≤0.27, 0.17≤c≤0.18, and 0.15≤d≤0.16.
