Lithium Cobalt Oxide (LiCoO₂) is a well-established and widely used cathode material in lithium-ion batteries. Known for its high energy density and stable electrochemical performance, LiCoO₂ has been instrumental in powering portable electronics for decades. Its layered crystal structure and efficient lithium-ion intercalation make it an ideal choice for compact, high-capacity battery applications.

What is Lithium Cobalt Oxide?

LiCoO₂ is a compound composed of lithium, cobalt, and oxygen, forming a layered structure that facilitates the easy movement of lithium ions during charge and discharge cycles. The material is synthesized through high-temperature solid-state reactions, often involving lithium carbonate and cobalt oxide as precursors.

Key Properties

• High Energy Density: Offers greater energy per unit volume, ideal for space-constrained applications.

• Stable Voltage: Delivers a stable operating voltage around 3.7V, supporting consistent performance.

• Good Cycle Life: Provides reliable performance over hundreds of charge-discharge cycles under proper conditions.

• Ease of Manufacturing: Well-known processing techniques make it a preferred choice for large-scale production.
