Lithium cobalt oxide is a chemical compound with the chemical formula of formula LiCoO2. Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid and is commonly used in the positive electrodes of lithium-ion batteries.
As all we may know lithium ion batteries are used in household electronics like mobile phones and laptop and these batteries are considered as the most promising energy storage and conversion device candidates for use in future electric vehicle applications because of having very high energy density.
In lithium ion batteries lithium cobalt oxide is one of the earliest founded lithium metal oxides used as cathode materials. The usage of lithium cobalt oxide started with the studies of Sony. Sony combined the lithium cobalt oxide cathode with a carbon anode and made the first successful lithium ion battery. It was a visionary study because this kind of battery now dominates the lithium battery market. Lithium cobalt oxide is preferred to use as cathode material in lithium ion batteries for its good performance and stability.
The studies on the usage of Lithium Cobalt Oxide Micron Powder for Li-ion Battery Cathode Application are still continued. Until now lithium cobalt oxide has been the subject of literally thousands of papers. Some studies are about the improvements in capacity and recharge ability of lithium cobalt oxide. One of the studies related to this field states that the capacity of lithium ion batteries where lithium cobalt oxide is used as cathode material could be improved by coating a metal oxide or phosphate on the surface of the lithium cobalt oxide particles.
