Development of carbon electrodes with high volumetric electrochemical performance is challenging for high-performance energy storage devices. In this work, we demonstrate a novel sucrose-derived porous carbon monolith (NPC-m) constructed by holey carbon nanosheets for super-high volumetric energy storages. NPC-m, derived from sucrose via a facile yet scalable and economic "bottom-up" synthesis route, exhibits a high specific surface area of 1376 m(2) g(-1), a narrow hole size distribution, and a high N content (similar to 6.65 at. %). Most importantly, a self-stacking density as high as 1.26 g cm(-3) can be achieved via simple drying processes. The electrodes based on NPC-m in carbon electrodes deliver super-high volumetric capacities of 1385 mAh cm(-3) (0.1 A g(-1)) for Li-ion batteries and 380 F cm(-3) (0.5 A g(-1)) for supercapcacitors, highlighting their great potentials for high-performance energy storages.
