Abstract
Special synthetic conditions at 0 °C were used to prepare nanostructured Li[Ni1/3Co1/3Mn1/3]O2 via chemical coprecipitation synthesis. The precursor preparation shows platelet shape with thickness of 10 nm and width of 100 nm. After calcination, the particles change to spherical or rectangle shape with a size of 100~200 nm. The nanostructured Li[Ni1/3Co1/3Mn1/3]O2 shows a well-ordered layered hexagonal lattice with low cation mixing. Galvanostatic testing showed good electrochemical properties and high rate capability, which may be due to its unique morphological and structural characteristics. Synthesis at 0 °C effectively prevented growth of the precursor particles and produced nanosize Li[Ni1/3Co1/3Mn1/3]O2, which gave improvement in high rate performance and favoring the future use of this cathode material for high power applications.
