Description |
Novel mixed hydroxy-carbonate (MHC) precursors were used to synthesis technique of LiNi1/3Mn1/3Co1/
3O2 cathode material. The powder X-ray diffraction (XRD) pattern of the synthesized LiNi1/3Mn1/3Co1/3O2
cathode materials exhibited a hexagonal cell with a = 2.8535 A˚ and c = 14.2040 A˚ . Fourier transform
infrared spectroscopy (FT-IR) spectrum of MHC and LiNi1/3Mn1/3Co1/3O2 consistent with vibration
modes of functional group. Presence of sub-micrometer particle size (200 nm) and highly crystalline
morphology confirmed using scanning electron microscopy (SEM). X-ray photoelectron spectroscopy
(XPS) suggested that oxidation state of the transition metals; Ni in +2, Mn in +4 and Co in +3 states,
respectively in LiNi1/3Mn1/3Co1/3O2 cathode materials. Cyclic voltammograms (CV) revealed only one
major redox couple at 4 V and suggested the absence of structural transitions from hexagonal to
monoclinic structure. The Li vs. LiNi1/3Mn1/3Co1/3O2 cell delivered an initial discharge capacity of
175 mAh g�1 in the voltage range 2.5–4.6 V @ 0.1 C.
