Nitrogen‐doping hierarchically porous carbon microspheres (PCMs) are constructed via a hydrothermal carbonization method with subsequent thermal annealing. Resulting from the interconnected hierarchical and open structure, an outstanding capacitive performance is achieved for PCM, which exhibits a superior specific capacitance and rate capability (397 and 288?F?g?1?at 0.5 and 20?A?g?1, respectively) and long cycling stability (about 95% capacitance retention after 10,000 cycles).

类红毛丹分层多孔碳微球作为高性能超级电容器的电极材料

通过水热碳化方法并随后进行热退火来构建氮掺杂的分级多孔碳微球（PCM）。由于相互连接的分层和开放式结构，PCM获得了出色的电容性能，它具有出众的比电容和速率能力（分别在0.5和20AAgg？1时分别为397和288A？F？g？1？）。）和长循环稳定性（10,000次循环后约95％的电容保持率）。
