Laser-induced graphene (LIG) is a three-dimensional porous material directly scribed from polymer materials by a CO₂ laser in the ambient atmosphere. We review the formation mechanism and factors of LIG to obtain the strategies of improving LIG microcosmic configuration to control the pore, composition, and surface properties of LIG, as well as the advancement in methodology to convert different carbon precursors to LIG. Based on the characteristics of LIG, the applications of LIG in a series of energy storage devices such as supercapacitors and batteries are highlighted. Up to now, with the deepening of LIG research, a system based on preparation of LIG with different substrates and composite material synthesis, and various applications has gradually been being formed.

激光诱导的石墨烯（LIG）是一种三维多孔材料，在环境大气中由CO ₂激光直接从聚合物材料划出。我们回顾了LIG的形成机理和因素，以获得改善LIG微观构型以控制LIG的孔，组成和表面性质的策略，以及将不同碳前体转化为LIG的方法学的进展。基于LIG的特性，重点介绍了LIG在一系列储能设备中的应用，例如超级电容器和电池。迄今为止，随着LIG研究的不断深入，基于不同基材的LIG制备和复合材料合成以及各种应用的系统逐渐形成。
