Three-dimensional reduced-graphene/MnO₂ prepared by plasma treatment as high-performance supercapacitor electrodes

Recent advancements in zero- to three-dimensional carbon networks with a two-dimensional electrode material for high-performance supercapacitors

“…As a result, carbon materials having great conductivity are employed to optimize the structural integrity and BP ake's conduction. [165][166][167] Yang et al utilized a simple sonication process to decorate exible black phosphorus nanoakes/CNT nanocomposite paper as a exible electrode for entirely solid-state ultracapacitors (ASSP). The constructed AASP was discovered to produce the highest power density of 821.62 W cm −3 , a C sp of 41.1 F cm −3 , and a high energy density of 5.71 mWh/cm 3 .…”

Chitosan-based oxygen-doped activated carbon/graphene composite for flexible supercapacitors

“…[2][3][4][5] Based on the charge storage mechanism, supercapacitors are classied as electrochemical double-layer capacitors (EDLCs), Faraday pseudocapacitors and hybrid supercapacitors. 6,7 Carbonaceous materials such as graphene have been widely investigated in the fabrication of supercapacitors because of its unique properties like high specic surface area (z2630 m 2 g À1 ), conductivity, mechanical exibility, and chemical stability. [8][9][10][11][12] However, graphene nanosheets as electrode material are inclined to restack due to the strong interaction in the nanoscale, which causes the decrease of the surface area and limits the performance of supercapacitors.…”

Further Thermal Reduction of Reduced Graphene Oxide Aerogel with Excellent Rate Performance for Supercapacitors

“…It was mainly due to aggregation and stacking of graphene sheets, largely reducing the specific surface area, which was difficult to avoid [14]. In consideration of this situation, one effective method was to prepare various composites based on 3DG via loading active electrode materials onto the 3DG framework, including transition metal compounds [15][16][17][18][19] and conducting polymers [20,21], etc. [22][23][24][25], for further improving the performance.…”
