For R&D scientists and product formulators in the battery sector, a deep understanding of the materials they utilize is fundamental. Lithium Cobalt Oxide (LiCoO2) powder, a vital cathode material for lithium-ion batteries, is no exception. Knowing its chemical composition, physical properties, and how these influence battery performance is crucial for successful development. As a dedicated supplier of battery raw materials, we provide insight into what makes our LiCoO2 powder an essential component for your research.

The Chemistry and Structure of LiCoO2

Lithium Cobalt Oxide (CAS 12190-79-3) possesses a layered hexagonal structure, where lithium ions are arranged between cobalt-oxygen layers. This specific arrangement dictates its electrochemical behavior. During discharge, lithium ions deintercalate from the anode and intercalate into the LiCoO2 cathode. The cobalt oxide component is responsible for accepting electrons, facilitating the overall electrochemical reaction. The purity of the LiCoO2 powder directly impacts the efficiency and cycle life of the battery. Impurities can lead to side reactions, increased internal resistance, and accelerated capacity fade. Therefore, sourcing from a reputable lithium cobalt oxide powder manufacturer that guarantees high purity is paramount for reliable R&D outcomes.

Key Physical and Electrochemical Properties for R&D

When evaluating LiCoO2 powder for battery applications, several physical and electrochemical properties are of significant interest to R&D professionals. These include:

  • Specific Surface Area (SSA): A higher SSA can improve reaction kinetics, but excessive surface area might lead to increased side reactions. Typical values range around 0.150 ± 0.100 m²/g.
  • Particle Size Distribution (PSD): Uniform PSD is essential for consistent electrode coating and slurry rheology. Parameters like D10, D50, and D90 provide insights into the particle size range.
  • Tap Density: Higher tap density (e.g., ≥2.700 g/cm³) contributes to increased volumetric energy density in the battery cell.
  • Electrochemical Performance: Crucial metrics include the first discharge specific capacity (e.g., ≥184.0 mAh/g) and the first charge-discharge efficiency (e.g., ≥94.00%). Good cycling performance, indicated by low capacity attenuation per cycle (<0.05%), is also vital for long-term battery life.

When you buy LiCoO2 cathode material, ensuring these parameters are well-defined and consistent is key to reproducible research. As your trusted lithium cobalt oxide supplier, we provide detailed technical specifications to support your R&D endeavors.

The Role of LiCoO2 in Battery Innovation

Lithium Cobalt Oxide remains a benchmark material for many portable electronic devices due to its balance of energy density, power capability, and relative cost-effectiveness. While research continues into alternative cathode materials, LiCoO2 continues to be a foundational element in battery innovation. Understanding its properties allows R&D teams to effectively formulate and test new battery designs. By sourcing high-quality LiCoO2 powder from a reliable CAS 12190-79-3 supplier in China, you ensure that your research is built upon a solid foundation of material excellence. The lithium cobalt oxide price for batteries should be considered in conjunction with the material's performance benefits, making it a strategic choice for many research projects.
