Laser-Induced Coal-Based Porous Graphene as Anode Toward Advanced Lithium-Ion Battery.

ABSTRACT: Graphene have been considered as the one of the most promising anode materials for the next generation lithium-ion batteries (LIBs) due to its unique properties compared to that of the commercial available graphite anode. However, the tedious preparation process, high cost and easy aggregation of 2D graphene caused by the strong van der Waals interactions among nanosheets affect the high reversible capacity of graphene for LIBs. Herein, a laser-induced strategy employing bituminous coal as a precursor for the preparation of porous graphene-based materials (LIG-B) is reported. LIG-B exhibits a porous foam-like structure and an enlarged interlayer spacing, which is larger than that of graphene with typical AB stacking. As the anode for LIBs, the LIG-B shows a high specific capacity of 400 mA
