摘要：
Mn-based carbonate precursor (Ni0.15Co0.15Mn0.7CO3) is synthesized by the carbonate precipitation in the presence of ethylene glycol. The nucleation and growth of precursor particles are investigated during the precipitation process by monitoring particle morphologies and structures. Primarily irregular-shaped and micron-sized loose agglomerate particles are formed and then the particles grow gradually and continue to aggregate with a round shape. After 3.5h, obvious segregation is observed within the agglomerations. Finally, the particles obtained after aging overnight have a spherical shape and dispersed with a narrow size distribution. The additive of ethylene glycol shows significant effects on the morphology of the prepared Ni0.15Co0.15Mn0.7CO3 and the electrochemical performance of lithiated Li1.2Ni0.12Co0.12Mn0.56O2.
