The Lithium ion cathode more widely spread is Li(Ni1/3Mn1/3Co1/3)O2, nevertheless more recently, research efforts have been targeted towards the development of new cathode compositions due to the high costs and toxicity associated with Cobalt.[1] The Li(NixMnyCo1-x-y)O2 cathode has received much interest as it is associated with lower manufacturing costs, fewer toxicity, higher capacity. Such cathode can be obtained by calcination of the precursor NixMnyCo1-x-y(OH)2 (NMC hydroxide) mixed with LiOH. It was shown that NMC oxide maintains the morphological characteristics of the precursor, for this reason it is important to study the precipitation process that leads to formation of particles of NixMnyCo1-x-y(OH)2, and the effects of the synthesis condition and mixing on the morphological characteristics of particles formed.
