Abstract
A novel lithium ion (Li-ion) battery cathode material has been investigated for potential mobile
technology energy storage applications. I have successfully synthesized Lithium Manganese oxide
(LMO), reduced Graphene Oxide (rGO) and Aluminium trifluoride (AlF3). The cathode coated
nanocomposite was compiled of the aforementioned materials to give [AlF3LiMn2O4-rGO]. A
single-phase spinel was observed from X-ray diffraction (XRD) studies with a high intensity (111)
plane which indicates good electrochemical activity. No alterations to the crystal structure were
observed after forming the composite nano-cathode material. Fourier transfer infrared (FTIR)
spectroscopy showed the vibrational spectrum of LiMn2O4 with a with asymmetric MnO6
stretching confirming that the spinel was formed.
