High Carbon 99% Spherical Graphite Powder For Li-Ion Batteries

Spherical Graphite Powder refers to a specific form of graphite powder that is processed to have a spherical morphology. This unique shape enhances its properties and makes it suitable for various applications, especially in lithium-ion batteries. Here are some general specifications and properties of Spherical Graphite Powder:

1. Particle Size: Spherical Graphite Powder typically has a narrow particle size distribution, with an average particle size ranging from a few to tens of micrometers. The specific particle size can be tailored to meet the requirements of different applications.

2. Tap Density: Spherical Graphite Powder exhibits high tap density, which refers to the density achieved when the powder is mechanically tapped. High tap density is desirable for improving the packing density and energy density in battery electrodes.

3. BET Surface Area: The specific surface area of Spherical Graphite Powder, as measured by the Brunauer-Emmett-Teller (BET) method, can vary depending on the manufacturing process and grade. It typically ranges from a few to several hundred square meters per gram.

4. Carbon Content: Spherical Graphite Powder is characterized by its high carbon content, typically exceeding 99%. The high carbon purity ensures excellent electrical conductivity and other desirable properties associated with graphite.

5. Tap Density: Spherical Graphite Powder exhibits high tap density, which refers to the density achieved when the powder is mechanically tapped. High tap density is desirable for improving the packing density and energy density in battery electrodes.

6. Electrochemical Performance: Spherical Graphite Powder exhibits excellent electrochemical performance, making it a preferred material for use in lithium-ion battery anodes. It offers high specific capacity, good cycling stability, and low irreversible capacity loss.

7. Thermal Expansion: Spherical Graphite Powder has relatively low thermal expansion, which is beneficial for maintaining the structural integrity of battery electrodes during cycling and thermal changes.

8. Shape Stability: The spherical morphology of Spherical Graphite Powder provides excellent shape stability, reducing the risk of electrode cracking or pulverization during battery operation.

It is important to note that specific specifications and properties of Spherical Graphite Powder can vary between manufacturers and product grades. When selecting Spherical Graphite Powder, it is recommended to refer to the supplier's technical data sheets and specifications for detailed information on particle size, carbon content, tap density, and other relevant properties.
