| Description |
In order to shorten process time and possibly reduce
synthesis cost of LiNi1/3Co1/3Mn1/3O2, the cathode material
was prepared by solution combustion and microwave
synthesis routes with reduced duration of calcination. The
products were also surface-modified with Al2O3 by a
mechano-thermal coating process to enhance cyclability.
The structure and morphology of the bare and the surfacemodified
LiNi1/3Co1/3Mn1/3O2 samples were characterized
by X-ray diffraction, field-emission scanning electron microscopy,
transmission electron microscopy, energy-dispersive
spectroscopy, and differential scanning calorimetry
techniques. At a 0.1-C rate and between 4.6 and 2.5 V, the
products delivered a first-cycle discharge capacity of as much
as 195 mA h/g. Surface modification of LiNi1/3Co1/3Mn1/3O2
with alumina resulted in improved cyclability.
