Ternary material, method for producing the same, battery paste, positive electrode, and lithium battery

摘要

A ternary material, a method for producing the ternary material, a paste for a battery, a positive electrode, and a lithium battery. The ternary material has a composition represented by a general formula LiNi1-xyCoxMyO2, wherein M is Mn or Al, 0 x 1, 0 y 1, x + y 1, and The ternary material includes particles of three stages from a small particle size to a large particle size, and the three-stage particles are formed by partially melting primary particles having a crystal structure and a plurality of primary particles. And a secondary sphere formed by agglomeration of the intermediate particles.
