Synthesis of r-GO-incorporated CoWO4 nanostructure for high-performance supercapattery applications

Facile hydrothermal synthesis of cobaltosic sulfide nanorods for high performance supercapacitors

“…Therefore, calculations based on the GCD curves can be performed to obtain a maximum volumetric energy density of 0.87 mW h cm −3 and a power density of 0.89 W cm −3 ( Fig. 4f ), which is superior to other recently reported devices, such as NiCoS/NF//r-GO-based ASCs (2.04 mW h cm −3 and 42.64 mW cm −3 ), 39 L-VN@AC//α-MnO 2 -based ASCs (8.5 mW h cm −3 and 34.3 mW cm −3 ), 40 CF/PPY//CNT/MnO 2 -based ASCs (0.27 mW h cm −3 and 24.1 mW cm −3 ), 41 CFF@V 2 O 5 //CFF@AC-based ASCs (0.928 mW h cm −3 and 17.5 mW cm −3 ), 42 MnO 2 /ZnO//rGO-based ASCs (0.234 mW h cm −3 and 133 mW cm −3 ), 43 CPCC@CuO@Mn(OH) 2 //CC@AC-based ASCs (0.18 mW h cm −3 and 18 mW cm −3 ). 44 All the results prove the high performance and practicality of the synthesized electrodes.…”

Multi‐Responsive Supercapacitors from Chiral Nematic Cellulose Nanocrystal‐Based Activated Carbon Aerogels

“…[23] On the contrary, supercapacitors (SCs) offer a high-power solution as they can work under high charge/discharge rates, operate adequately over a wide range of temperatures, experience little performance degradation during cycling, have enhanced safety with no risk of thermal runaway, and show limited toxicity by avoiding organic electrolytes. [24] SCs can be fabricated using activated carbon (AC) derived from renewable materials such as cellulose [25,26] or graphitic materials [27][28][29][30] and require little maintenance. Consequently, they find applications in rural areas without reliable public power grids, [26] in portable devices and hybrid vehicles, [25] and in situations where rapid power delivery is essential, such as the operation of emergency doors on Airbus A380 aircraft.…”
