Lithium Ion Battery Material

Lithium cobalt oxide nanoparticles, LiCoO2, has been considered one of the most suitable cathode materials in Li-ion secondary batteries. The performance of the cathodes is affected by a number of factors such as particle size and crystalline phase of the material. Smaller particle size distribution resulted in better cycle stability used two LiCoO2 electrodes with different particle size distributions (2–4 and 5–10 µm) as the cathodes.

Lithium cobalt oxide nanoparticles (LiCoO2) has been widely studied as a cathode material for lithium-ion secondary batteries since it has good capacity, high specific energy, good power rates, low self-discharge, and excellent cycle life. LiCoO2 exhibits two forms viz. hexagonal and cubic structures. These structures are based on some oxide sublattice and are distinguished by the spatial arrangements of cations.

Hollow nanospheres of lithium cobalt oxide nanoparticles have been investigated as materials for gas sensor electrodes, for the detection of toluene, acetone, and other organic vapors. Lithium cobalt oxide nanoparticles anchored on single-walled carbon nanotubes have been investigated for sensing nitrogen oxides and hydrogen. This application takes advantage of the reactivity between the gas and the oxide, as well as the electrical connection with the substrate (both being p-type semiconductors).

Lithium Cobalt oxide nanoparticles, such as nanotubes, offer high surface-to-volume ratio and short path length for lithium cation transport, leading to high reversible capacity and good cycle life. The particles may incorporate other substances, as for example diphenylalanine/cobalt oxide hybrid nanowires. Lithium Cobalt Oxide (Co3O4) nanoparticles anchored on a single sheet of graphene.
