ABSTRACT

The LiMn1.5Ni0.5O4, substituting a part of Mn with Ni in the LiMn2O4, the spinel structure has good chargedischarge cycle stability and high discharge capacity at 4.7 V. In this study LiMn1.5Ni0.5O4 powders were synthesized by polymerization complex method. The effect on the characteristics of synthesized LiMn1.5Ni0.5O4 powders was studied with citric acid (CA) : metal ion (ME) molar ratio (5 : 1, 10 : 1, 15 : 1, 30 : 1) and calcination temperature (500~900oC). Single phase of LiMn1.5Ni0.5O4 was observed from XRD analysis on the powders calcined at low (500oC) and high temperatures (900oC). The crystalline size and crystallinity increased with calcination temperature. At low calcination temperature the particle size decreased and specific surface area increased as the CA molar ratio increased. On the other hand, high particle growth rate at high calcination temperature interfered the particle size reduction and specific surface area increase induced by the increase of CA molar ratio.
