摘要
Abstract
Using Al2 (SO4) 3 as aluminum source,ammonia as precipitant and ammonium oxalate as chelating agent,a coating layer was formed on the surface of Ni0.6 Co0.2 Mn0.2 (OH) 2 particles by wet-way precipitation method,according to the theory of heterogeneous nucleation.The agglomeration of Al(OH) 3 and the adhesion between coated particles were improved,the influence of coating on the tap density and particle sizes of the material was reduced.The uniform and dense coating layer was formed when the mole ratio of ammonium oxalate and Al2 (SO4)3 was 3∶ 1.The shell like structure was formed when the content of Al was 1%.The network structure and the dot coating structure were formed when the content of Al were 0.5% and 0.3%.关键词
