Impurity Limitation Standard of Battery Grade Carbon Raw Materials
New energy battery factories set strict limits on sulfur and ash content of raw carbon materials. Excessive sulfur will trigger battery self-discharge, shorten cycle service life and lower finished product qualification rate. Low sulfur petroleum coke can perfectly meet the ultra-low impurity threshold of artificial graphite production.
Stable Supply Chain Supports Mass Battery Production
As power storage and EV industries expand rapidly, manufacturers have higher demand for continuous low-sulfur coke supply. We maintain long-term cooperation with low-sulfur oil refineries to guarantee stable raw material sources without frequent index fluctuation.
Comprehensive Cost Comparison of Low Sulfur Coke for Graphitization
Although low sulfur coke has a higher unit price, it reduces waste rate in follow-up graphitization processing. Factories can cut extra loss caused by unqualified graphite, bringing better overall economic benefits in long-term mass production.
Global Export Demand Trend for Low Sulfur Coke
Europe, Southeast Asia, and North America battery material enterprises keep increasing orders of low-sulfur calcined coke. Our customized particle size and full inspection reports simplify overseas customers’ incoming inspection procedures.
