Hard carbon anode material for sodium-ion and lithium-ion batteries PURESTAR is at the forefront of hard carbon development for next-generation batteries. Our hard carbon anode materials are engineered for:
Sodium-ion batteries (SIBs) – high reversible capacity (> 300 mAh/g) and excellent cycling stability
Lithium-ion batteries – fast-charging anodes with low expansion rates
Supercapacitors – high surface area carbon for electric double-layer capacitors
Derived from biomass precursors through controlled pyrolysis and activation, our hard carbon features optimized interlayer spacing (0.38–0.40 nm) for efficient Na⁺ intercalation, making it ideal for grid-scale energy storage and electric vehicle applications.
2.Gold Recovery
Activated carbon in gold mining CIP and CIL recovery circuits PURESTAR's gold recovery activated carbon is the industry standard for Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), and Carbon-in-Column (CIC) gold extraction circuits:
Gold adsorption capacity: > 8,000 g Au/t carbon
Superior hardness: > 98% abrasion resistance (ASTM D5261) to minimize carbon fines and gold losses
Optimized particle size: 6×12 mesh and 8×16 mesh for rapid kinetics and efficient elution
Low platelet content: reducing preg-robbing of gold-cyanide complexes
Our carbon is used by major mining operations across Africa, Central Asia, and South America, with technical support for carbon inventory optimization and regeneration circuit design.
