3D (Three-dimensional) sandwich-structured of ZnO (zinc oxide)/rGO (reduced graphene oxide)/ZnO for high performance supercapacitors

Fabrication of polyaniline nanowire/TiO2 nanotube array electrode for supercapacitors

“…4B shows the GCD curves at a discharge current of 18 mA. The specific capacitances of the four electrodes were measured using the following relationship [46]:…”

One-pot electrodeposition synthesis of ZnO/graphene composite and its use as binder-free electrode for supercapacitor

“…[26] However, the whole of preparation process discussed above involve two different steps, including the reduction of graphene oxide (GO) and the following insertion of ZnO nanostructure by various synthesis techniques. Furthermore, in many previous reports, [25,[30][31][32] the supercapacitors electrodes are usually fabricated by coating the mixture of polymer conductive additive with active materials to the collectors, the introduction of polymer binder increases the adhesion strength of the electrode but at the expense of the electrode's conductivity and electrochemical performance.…”

Enhanced electrochemical performances of cylindrical hybrid supercapacitors using activated carbon/ Li 4-x M x Ti 5-y N y O 12 (M = Na, N = V, Mn) electrodes

“…On the contrary, although the supercapacitors have attractive advantages of power density and cycle performance, it also has a critical drawback of low energy density [3e5]. Therefore, in order to overcome the shortcomings of LIBs and supercapacitors, the hybrid supercapacitors having synergetic effect from both LIBs and supercapacitors were designed as a next generation energy storage devices [5]. In hybrid supercapacitors, the lifespan is a key issue and depends on the anode derived from LIBs, because activated carbon derived from supercapacitors shows the semi-permanent life during chargeedischarge process [6].…”
