研究了石墨化碳纳米管（g-CNTs）作为水不对称超级电容器MnO2复合阴极的电极载体。通过优化g-CNTs上石墨烯叶状层的密度，可以调节电极的性能，从而实现对MnO2电沉积的通用/形态控制。g- cnt混合结构的协同作用和优化导致了高MnO2比负载（2.3 mg/cm(2)）下的高比阻（640 F/g），从而创造了改善实际性能的独特途径：
Graphenated- carbon nanotubes (g-CNTs)Avore inVeStigated as the electrode Support in MnO2 composite -cathodes for aqueous asymmetric supercapacitors. The, electrode performance,could be tuned by optitnizing the density of graphene foliates on the g-CNTs, which enabled geernetric/morphologic control over the MnO2 electro-deposits. The synergy and optimization of the g-CNT hybrid Structure led to a high specific opadtance (640 F/g) at high MnO2 specific loading (2.3 mg/cm(2)), thus creating a uoique pathway toward improved practical performance:
