Abstract
This application relates to an electrode active composition, a preparation method thereof, an electrode, a battery, and an apparatus. The electrode active composition includes: a first component, the first component being lithium cobalt oxide particles; and a second component, the second component being ternary material particles. The first component includes lithium cobalt oxide particles with a particle size greater than 11 μm and lithium cobalt oxide particles with a particle size less than 6 μm, and a ratio in number of the lithium cobalt oxide particles with a particle size greater than 11 μm to the lithium cobalt oxide particles with a particle size less than 6 μm is 0.2-4.8, and in some embodiments, 0.2-2.8. A summed number of the lithium cobalt oxide particles with a particle size greater than 11 μm and the lithium cobalt oxide particles with a particle size less than 6 μm accounts for above 90% of a total number of particles in the first component.
