Laser-Induced Porous Graphene-Based Materials and Its Potential Application in Lithium-Ion Batteries.

ABSTRACT: Laser-induced coal-based graphene (C-LIG) is a promising field in energy materials research that focuses on converting abundant coal resources into high-value graphene-based materials using low-cost and environmentally friendly processes. In this study, we successfully produced few-layer graphene from low-volatility bituminous coal under vacuum conditions using carbon dioxide infrared laser equipment. The results showed that the laser-induced graphene consists predominantly of 2-5 layers, featuring multipore structures with smaller-size pores on the pore walls. It also exhibits large interlayer spacing with the layers arranged in a long-range disorder, demonstrating high crystallinity and significant expansion of the aromatic layers. Notably, the interlayer spacing increases as the number
