Lithium composite oxides, producing method thereof, and lithium secondary battery having the same as active material of cathode |
| abstract |
Adding ammonia water as a complex and an alkaline solution as a pH adjusting agent to the mixed aqueous solution of cobalt salt and nickel salt, coprecipitating and initial extraction to form a nickel-cobalt composite hydroxide forming needle-shaped primary particles to form amorphous secondary particles. Lithium composite prepared by the method comprising the step of first heat treatment at 280-420 ℃ by adding lithium hydroxide to the composite hydroxide, and the second heat treatment at 650-750 ℃ the result obtained by the first heat treatment The oxide (LiNi (1-xy) Co x M y O 2 (M = Al, Ca, Mg and B is at least one metal atom selected from x, 0.1 is 0.3 to 0.3, y is 0 to 0.1)) Primary particles are laminated to form amorphous secondary particles, and the average particle size of the primary particles and the secondary particles is small, so that a lithium ion secondary battery using this lithium composite oxide as a positive electrode active material has a high capacity. |
