Bottom-up-synthesized graphene nanoribbons (GNRs) with excellent electronic properties are promising materials for energy storage systems. Herein, we report bottom-up-synthesized GNR films employed as electrode materials for micro-supercapacitors (MSCs). The micro-device delivers an excellent volumetric capacitance and an ultra-high power density. The electrochemical performance of MSCs could be correlated with the charge carrier mobility within the differently employed GNRs, as determined by pump–probe terahertz spectroscopy studies.

用于超高功率微型超级电容器的自下而上、表面合成的扶手椅石墨烯纳米带

自下而上合成的石墨烯纳米带（GNRs）具有优异的电子特性，是用于储能系统的有前途的材料。在此，我们报告了用作微型超级电容器 (MSC) 电极材料的自下而上合成的 GNR 薄膜。该微型器件具有出色的体积电容和超高功率密度。MSCs 的电化学性能可能与不同使用的 GNRs 内的电荷载流子迁移率相关，如泵浦探针太赫兹光谱研究所确定的。
