Status and Prospects of Laser-Induced Graphene for Battery Applications

Synthesis of 3D graphene by laser irradiation has emerged as a promising approach due to its multifunctionality, cost effectiveness, and simplicity. Herein, the emerging applications of laser-induced graphene (LIG) in batteries are focused on. 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, the article concludes by giving the authors' perspectives and outlook for developing this class of carbon materials for advanced battery systems.
