First claim
Opening claim text (preview).
The invention claimed is: 1. A transition metal precursor for preparation of a lithium transition metal oxide, wherein precursor particles constituting the transition metal precursor are transition metal hydroxide particles, wherein the transition metal hydroxide particles are a compound represented by Formula 2 below: M(OH 1-x ) 2 (2) wherein M consists of nickel (Ni), cobalt (Co), and manganese (Mn); and 0≤x≤0.5; and wherein a tap density of the transition metal precursor is from 1.3 g/cc to 1.6 g/cc, and a ratio of tap density to average particle diameter D50 of the precursor satisfies a condition represented by Equation 1 below: 2000 < Tap density Average particle diameter D 50 of transition of metal precursor < 3500 ( g / cc · cm ) . ( 1 ) 2. The transition metal precursor according to claim 1 , wherein the transition metal precursor has an average particle diameter D50 of 1 to 30 μm.
