Bottom-up-synthesized graphene nanoribbons (GNRs) with excellent electronic properties are promising materials for energy storage systems. Herein, we report 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.
具有优异电子性能的自下而上合成的石墨烯纳米带（GNRs）是储能系统中有前景的材料。在此，我们报道了用作微型超级电容器（MSCs）电极材料的GNR薄膜。该微型器件具有优异的体积电容和超高功率密度。通过泵浦-探测太赫兹光谱研究确定，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。
