Supercapacitors have been widely studied around the world in recent years, due to their excellent power density and long cycle life. As the most frequently used electrode materials for supercapacitors, carbonaceous materials attract more and more attention. However, their relatively low energy density still holds back the widespread application. Up to now, various strategies have been developed to figure out this problem. This research news summarizes the recent advances in improving the supercapacitor performance of carbonaceous materials, including the incorporation of heteroatoms and the pore size effect (subnanopores' contribution). In addition, a new class of carbonaceous materials, porous organic networks (PONs) has been managed into the supercapacitor field, which promises great potential in not only improving the supercapacitor performances, but also unraveling the related mechanisms.
近年来，超级电容器因其优异的功率密度和长循环寿命而在全球范围内得到了广泛研究。作为超级电容器最常用的电极材料，碳材料引起了越来越多的关注。然而，其相对较低的能量密度仍然阻碍了其广泛应用。到目前为止，已经开发了各种策略来解决这个问题。本研究新闻总结了提高碳材料超级电容器性能的最新进展，包括杂原子的掺入和孔径效应（亚纳米孔的贡献）。此外，一类新型的碳材料，即多孔有机网络（PONs）已经被引入超级电容器领域，这不仅有望提高超级电容器的性能，而且还能揭示相关的机制。
