| Sumario: | Lithium cobalt oxide (LiCoO2
) is one of the most relevant components
in lithium-ion batteries. The array of sought-after features of LiCoO2
depends on its synthesis method. In this work we synthesized and
characterized a nanocrystalline LiCoO2
oxide obtained with a wet
chemistry synthesis method. The oxide obtained was a homogeneous
powder in the nanometric range (5-8 nm) and exhibited a series of
improved properties. Characterization by FTIR and UV-Vis techniques
led to identifying citrate species as main products in the first step of the
synthesis process. X-ray diffraction (XRD), Raman, and transmission
electron microscopy (TEM) characterizations led to identifying a pure
crystalline phase of the synthesized LiCoO2
oxide. Steady state electrical
characterization and solid-state impedance spectroscopy determined the
high conductance of the synthesized oxide. All these features are desirable
in the design of cathodes for lithium ion batteries.
