High-Purity Graphite Powder for Lithium-Ion Battery Applications
BZN5 is an ultra-high-purity synthetic graphite powder developed by BZNCarbon for use in lithium-ion battery anode formulations. Engineered with a fine particle size distribution and exceptional crystallinity, BZN5 enables outstanding electrical conductivity, structural stability, and long-term cycling performance.
Its low moisture, ash, and metallic impurity levels make it highly reliable for next-generation battery cells, especially in applications demanding high energy density, safety, and consistent performance.
Description
What is BZN5?
BZN5 is a finely milled synthetic graphite designed to function as a conductive additive or base component in lithium-ion battery anodes. Due to its highly crystalline layered structure and narrow particle size distribution, it delivers excellent electrochemical efficiency with minimal irreversible capacity loss.
The material’s extremely low iron and transition metal content helps prevent electrolyte degradation and extends the lifespan of lithium-ion cells.
Key Applications
BZN5 is ideal for use in:
Lithium-Ion Battery Anodes
Enhances conductivity and structural integrity in cell chemistries based on natural or artificial graphite.Electric Vehicle Battery Cells
Optimized for high-capacity, long-cycle, and fast-charging automotive battery systems.Consumer Electronics Batteries
Ensures stability and safety in compact batteries for smartphones, tablets, laptops, etc.Energy Storage Systems (ESS)
Suitable for stationary storage applications in renewable integration, backup systems, and grid balancing.Battery R&D and Pilot Production
Used as a benchmark-grade powder in the development and testing of lithium and sodium-ion technologies.
