Research on Graphene and its importance in the field of energy conversion and storage devices such as fuel cells, batteries, supercapacitors and solar cells has gained momentum recently. It is studied to be the most suitable electrode material for enhanced performance of supercapacitors in terms of charge–discharge cycles, specific capacitance, high power and energy densities and so on, specifically due to its high conductivity and large theoretical surface area. Unfortunately, it posits lot of challenges due to its irreversible stacking between the individual sheets resulting in the decrease in the Specific Surface Area (SSA) compared to the theoretically reported values. Numerous studies have been carried out to prevent this stacking in order to increase the surface area, thereby being a more suitable material for the manufacture of electrodes for supercapacitors as its capacitance greatly depends on the electrode material. To solve this problem, the conversion of two-dimensional graphene sheets to three-dimensional crumpled graphene structure has been verified to be the most effective approach. The study of crumpled graphene has been one of the recent trends in the field of energy storage applications in consumer electronics and hybrid vehicles as the process of crumpling can be controlled to suit the prospective device applications.

近年来，石墨烯的研究及其在能量转换和存储设备（例如燃料电池，电池，超级电容器和太阳能电池）领域的重要性得到了发展。在充放电循环，比电容，高功率和能量密度等方面，它被认为是增强超级电容器性能的最合适的电极材料，特别是由于其高电导率和较大的理论表面积。不幸的是，由于其在单张纸之间的不可逆堆叠，导致比表面积（SSA）与理论上报道的值相比降低，因此提出了很多挑战。为了增加表面积，已经进行了许多研究来防止这种堆积，由于其电容极大地取决于电极材料，因此是制造超级电容器电极的更合适的材料。为了解决这个问题，已经证明将二维石墨烯片转变为三维皱缩的石墨烯结构是最有效的方法。皱纹石墨烯的研究一直是消费电子产品和混合动力车辆中储能应用领域的最新趋势之一，因为可以控制皱纹的过程以适应预期的设备应用。
