| titleOfInvention | Positive electrode active material for secondary battery and secondary battery including the same |
| abstract | The present invention provides a positive electrode active material for a secondary battery including lithium composite metal oxide particles represented by the following formula 1, and a secondary battery including the same. [Formula 1] Li a Ni 1‑x‑y Co x M1 y M2 z M3 w O 2 In formula 1, M1 is a metal element whose surface energy (ΔE surf ) calculated by the following formula 1 is -0.5 eV or more, M2 is a metal element whose surface energy (ΔE surf ) calculated by the following equation 1 is -1.5eV or more and less than -0.5eV, M3 is a metal element whose surface energy (ΔE surf ) is less than -1.5eV calculated by the following equation 1, And 1.0≤a≤1.5, 0<x≤0.5, 0<z≤0.05, 0.002≤w≤0.1, 0<x+y≤0.7. [Equation 1] ΔE surf =E surf2 -E surf1 =(E slab2 -E bulk ) -(E slab1 -E bulk ) In the above equation 1, E surf2 represents the maximum amount of the metal element toward the lithium composite metal oxide particles The degree of orientation of the outer surface, E surf1 represents the degree of orientation of the metal element toward the center of the lithium composite metal oxide particle, and E slab1 is when the metal element is in the center of the lithium mixed metal oxide particle. the energy of the slab model of the lithium composite metal oxide particle, E slab2 is the energy of the slab model of the lithium composite metal oxide particle when the metal element is on the outermost surface of the lithium composite metal oxide particle, And E bulk is the energy of the bulk model corresponding to each plate model. |
