The Science Behind Super C65’s Performance
Structure and Surface Properties
Super C65’s performance is rooted in its microscopic structure. Unlike simple carbon black, its particles form clusters or aggregates that enhance conductivity and mechanical strength. These aggregates consist of covalently bonded carbon atoms, making them highly resistant to fragmentation during material processing.
The particle size of Super C65 typically ranges from 10 to 100 nm, with a surface area of up to 1500 m²/g. Smaller particles with larger surface areas exhibit higher conductivity and better ultraviolet absorption, while maintaining excellent dispersibility in battery electrodes.
Production Process
Super C65 is derived from conventional carbon black through advanced refining techniques. The base material is produced via the partial combustion or thermal decomposition of hydrocarbons under controlled conditions. This process yields a fine black powder with varying particle sizes and surface properties. The resulting material is then purified and optimized to meet the stringent requirements of lithium-ion battery applications.
