Details

This product is a single-crystal lithium cobalt oxide (LCO) cathode material specifically designed for high-rate applications. Its small particle size and large specific surface area facilitate rapid lithium-ion insertion and extraction, resulting in excellent rate capability and cycling stability. Compared to conventional LiCoO₂, this material requires a higher proportion of conductive agents and binders in the electrode formulation to ensure efficient electronic transport, and its electrode compaction density is approximately 0.3–0.5 g/cc lower. It demonstrates good processability and stable quality, making it suitable for commercial mass production. Common applications include high-rate devices such as drones and electronic cigarettes, and it is also convenient for pouch cell and coin cell research in laboratory settings. Storage should be under sealed conditions at room temperature, with a shelf life of two years. A compatible electrolyte, such as lithium cobalt oxide electrolyte (KLD-1376), is recommended for optimal performance.

1. Due to the small particle size and large specific surface area of the material, compared with the positive electrode formula of ordinary LiCoO2, more conductive and adhesive agents are required to ensure good electronic transmission network.

2. Due to the small particle size, the compaction density of the electrode sheet is 0.3-0.5g/cc lower than that of conventional LiCoO2.

1. MA-EN-CA-0R lithium cobalt oxide, single crystal structure, with small particle size and large specific surface area, facilitating rapid insertion and extraction of lithium ions, resulting in excellent rate performance and good cycling stability.

2. Good processability and stable quality for commercial mass production.

3. Widely used in high-rate requirement products such as drones and electronic cigarettes.

4. Convenient for research on pouch cells and coin cells.
