▎ 摘　　要

Defect-introduced graphene sheets with hole structure were fabricated utilizing a facile and scalable Cobalt catalyzed gasification strategy. The holes unleash the Li insertion potential by providing pathways for Li into the overlaps and wrinkles of graphene sheets. As a consequence, the advanced anode material exhibits first reversible specific capacity as high as 1009 mAh g(-1) and can reach 898 mAh g(-1), 667 mAh g(-1), 453 mAh g(-1) at current densities of 300 mA g(-1), 500 mA g(-1) and 1000 mA g(-1), respecively. As far as we know, the defect-introduced graphene sheets are firstly fabricated as anode in lithium-ion batteries. (C) 2015 Elsevier B.V. All rights reserved.
