We prepared a material composed of high-density holey graphite nanosheets (HGNs) that supports a high gravimetric capacitance of 295 F g and a volumetric capacitance of 384 F cm for use as electrodes in supercapacitor devices. This method is a simple and scalable route to obtain large amounts of holey two-dimensional materials with high electrochemical performances.
我们制备了一种由高密度多孔石墨纳米片（HGNs）组成的材料，该材料用作超级电容器装置的电极时，具有295 F g的高比电容和384 F cm的体积电容。此方法是获得大量具有高电化学性能的多孔二维材料的简单且可扩展的途径。
