Lithium Cobalt Oxide

Lithium Cobalt Oxide (LiCoO₂) is a key cathode material in lithium-ion batteries, widely known for its high energy density, stable electrochemical performance, and long cycle life. Its layered crystal structure allows lithium ions to move in and out of the material, facilitating efficient charge and discharge cycles.

Physical Properties:

Chemical formula：LiCoO2

Molar mass： 97.87 g mol−1

Purity: Often manufactured at purities of 99.9% or higher for optimal electrochemical performance in high-end battery applications.

Appearance: Typically a dark gray to black powder.

Density: Approximately 4.8 g/cm³.

Crystal Structure: Lithium Cobalt Oxide (LiCoO₂) has a layered hexagonal structure that promotes efficient lithium-ion intercalation and deintercalation, key for its function as a battery cathode.

Applications:

Consumer Electronics: Lithium Cobalt Oxide (LiCoO₂) is commonly used in batteries for smartphones, laptops, and cameras, where its high energy density and reliability make it ideal for portable devices.

Electric Vehicles (EVs): Although newer materials like lithium iron phosphate (LFP) and nickel-cobalt-aluminum (NCA) are often preferred in EVs, LiCoO₂ has been used in early EV designs and is still present in some plug-in hybrid applications.

Medical Devices: Its stability and predictable performance make LiCoO₂ a suitable choice for batteries in certain medical devices and sensors.

Research and Development: Lithium Cobalt Oxide (LiCoO₂) is commonly studied in battery research, as it serves as a model compound for understanding lithium-ion behavior, degradation, and potential improvements in battery design.
