Positive active material for lithium secondary battery and lithium secondary battery containing the same |
| abstract |
PROBLEM TO BE SOLVED: To provide a positive electrode active material for a lithium secondary battery capable of improving low temperature stability while maintaining an excellent reversible capacity of LiNiO 2 , and a lithium secondary battery including the same. The positive electrode active material includes a plurality of secondary particles composed of primary particles that are lithium-based composite oxides having a single crystal structure, and the density of crystal grain boundaries is within the secondary particles. When the number of grain boundaries between the primary particles is divided by the number of the primary particles forming the secondary particles, the crystal grains among the plurality of secondary particles forming the positive electrode active material A positive electrode active material for a lithium secondary battery, wherein the ratio of the secondary particles having a field density of 0.5 or less is 30% or more.
