Title:

リチウム二次電池用正極活物質組成物及びこれを含むリチウム二次電池

Document Type and Number:

Japanese Patent JP6810120

Kind Code:

B2

Abstract:

To provide a positive electrode active material composition for a lithium secondary battery and a lithium secondary battery including the same, and more specifically, a positive electrode active material composition for a lithium secondary battery and a lithium secondary battery including the same including a mixture of particles heat treated at the same temperature with different Ni composition and particle size.SOLUTION: According to the present invention, it is possible to adjust the Ni content of large particles and small particles to similarly adjust the optimum volume development temperature of large particles and small particles, thereby manufacturing a lithium secondary battery having improved output and life.SELECTED DRAWING: Figure 1
