Synthesis of 3D graphene by laser irradiation has emerged as a promising approach due to its multifunctionality, cost-effectiveness and simplicity. In this review, we focus on the emerging applications of laser-induced graphene (LIG) in batteries. This type of 3D graphitic carbon offers several advantages, including (1) binder-free self-supported electrode configuration, (2) high electrical and ionic conductivity, (3) hierarchical porosity, and (4) controllable composition upon laser exposure. A comprehensive review of the current status of LIG synthesis and its development for battery applications is discussed. This includes using LIG as an electrode for lithium and sodium ion batteries, a current collector for lithium metal batteries, an electrocatalyst for metal-air batteries, and a host and interlayer for lithium-sulfur batteries. Finally, we conclude by giving our perspectives and outlook for developing this class of carbon materials for advanced battery systems.
