Abstract
Phosphorus-doped soft carbons were successfully prepared by carbonizing petroleum cokes treated with phosphorus acids, such as H3PO2, H3PO3, and H3PO4. The effect of the type of phosphorus acids used on the composition, structure, and electrochemical performance of the soft carbons was extensively investigated. The soft carbons modified with H3PO3 and H3PO4 exhibited dramatically improved reversible capacities and outstanding rate capabilities.
