Why Low-Sulfur CPC Is Indispensable for Artificial Graphite
Lithium battery anodes require ultra-low impurity raw materials. Sulfur over 0.5% will cause self-discharge, capacity decay and shortened cycle life. Low-sulfur calcined coke with S≤0.5% ensures stable electrochemical performance after high-temperature graphitization.
Production Standard Control for Battery-Grade CPC
We strictly screen low-sulfur green coke raw materials and maintain precise kiln temperature at 1250–1350℃ to control ash below 0.5% and real density 2.08–2.15 g/cm³, fully matching graphitization factory technical standards.
Complete Industrial Chain Matching for New Energy Factories
Our low-sulfur CPC can be crushed into custom powder sizes, supporting continuous mass supply for graphitization workshops, with full COA test reports provided per shipment for incoming inspection.
Market Demand Trend of Battery-Grade Calcined Coke
With fast expansion of power battery and energy storage industry, low-sulfur calcined petroleum coke maintains stable growing global demand, becoming a must-have carbon raw material for new energy material manufacturers.
