摘要
Ginkgo leave, a naturally abundant resource, has been successfully employed as the raw material to prepare ni- trogen doped porous carbon （NDPC） materials. The preparation of the porous carbon does not involve assistance of any activation or template technique. The as-obtained NDPC shows favorable features for electrochemical energy storage, which can not only provide multiple sites for the storage and insertion of Li ions, but also facilitate rapid mass transport of electrons and Li ions. As a result, the NDPC when evaluated as an anode material for lithium ion batteries delivers high reversible capacity （505 mAh·g-1 at 0.1 C）, excellent rate capability （190 mAh·g-1 at 10 C）. These favorable properties suggest that the NDPC can be a promising anode material for lithium ion batteries （LIBs）.
