Abstract
A positive electrode active material includes olivine lithium manganese iron phosphate, wherein the olivine lithium manganese iron phosphate contains a first dopant at the phosphorus site and a second dopant at the manganese-iron site, and satisfies relationships of ΔG<sup>3</sup> < ΔG<sup>1</sup> + ΔG<sup>2</sup>, ΔG<sup>2</sup> < 0 kJ/mol, and ΔG<sup>3</sup> < 0 kJ/mol where ΔG<sup>1</sup> represents free energy of formation produced by substitution of phosphorus at the phosphorus site with the first dopant, ΔG<sup>2</sup> represents free energy of formation produced by substitution of iron at the manganese-iron site with the second dopant, and ΔG<sup>3</sup> represents free energy of formation produced by substitution of phosphorus at the phosphorus site with the first dopant and substitution of iron at the manganese-iron site with the second dopant.
