Asphaltene-derived materials have been successfully demonstrated as effective anode materials for Li-ion batteries. Pyrolyzed asphaltene used as an anode exhibited a specific capacity of up to 420 mAh g−1, significantly surpassing that of well-known commercial graphite and raw asphaltene. The battery anode made from pyrolyzed asphaltene also displayed excellent rate capabilities, even at a high 5 °C-rate. Both pyrolyzed asphaltene and N-doped pyrolyzed asphaltene demonstrated strong cycle performance, underscoring their potential as high-performance anode materials.

摘要

Asphaltene-derived materials have been successfully demonstrated as effective anode materials for Li-ion batteries. Pyrolyzed asphaltene used as an anode exhibited a specific capacity of up to 420 mAh g−1, significantly surpassing that of well-known commercial graphite and raw asphaltene. The battery anode made from pyrolyzed asphaltene also displayed excellent rate capabilities, even at a high 5 °C-rate. Both pyrolyzed asphaltene and N-doped pyrolyzed asphaltene demonstrated strong cycle performance, underscoring their potential as high-performance anode materials.
