A Study of LiMn(2-X)FexO4 Cathodic Nano Material for Lithium-Ion Batteries

Abstract

LiMn1.5Fe0.5O4is synthesized using sol-gel method and annealed at 850°C for 24 hours. It is then characterized using X-ray diffraction (XRD) and charge discharge analysis. The bulk material are then proceed to further grinding to become nanosize. The nanosample is then characterized using XRD and charge discharge performance, and the specific capacities of the two materials are compared. nanosample of LiMn1.5Fe0.5O4shows higher specific capacity which is 160.16 mAhg-1compares to the bulk which gives only 128.663mAhg-1. This shows that with smaller particle size, the battery performance has improved in terms of its capacity.
