Ultra-long-term cycling stability of an integrated carbon–sulfur membrane with dual shuttle-inhibiting layers of graphene “nets” and a porous carbon skin

Abstract

An integrated carbon-sulfur (CSG/PC) membrane with dual shuttle-inhibiting layers was prepared by inserting graphene "nets" and a porous carbon (PC) skin, and the membrane achieved an extraordinary cycling stability up to 1000 cycles with an average Coulombic efficiency of ∼100%.

2D MXenes as Co-catalysts in Photocatalysis: Synthetic Methods

“…Energy shortage and environmental pollution have become the two major issues faced by humanity due to limited fossil fuel resources and increasing consumption. Developing sustainable and clean energy is the key to addressing these two problems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In being clean and inexhaustible, solar energy shows great potential to be one of the most promising future energy sources.…”

High-performance coaxial wire-shaped supercapacitors using ionogel electrolyte toward sustainable energy system

“…Furthermore, ionogel utilized as solid-state electrolyte exhibits high thermal/electrochemical stability, which effectively ensures the great reliability and high operating voltage of coaxial WSSCs. Compared with other energy conversion and storage units [59,60,61,62,63,64,65,66], coaxial WSSCs not only show superior flexibility and wearability but also exhibit low resistance, high volumetric energy density (3.2 mW h/cm 3 ), and strong durability (82% after 10,000 cycles). More importantly, the coaxial WSSCs device with high voltage of 3 V can be effectively recharged by harvesting sustainable wind source and repeatedly supply power to the lamp without a decline of electrochemical performance.…”

Stable Dispersed Zeolitic Imidazolate Framework/Graphene Oxide Nanocomposites in Ionic Liquids Resulting in High Lubricating Performance

“…Graphene oxide (GO) has a nanometer‐scale thick‐layered structure and strong hydrophilicity. Owing to its 2D structure and abundant number of functional groups, it exhibits great potential in a plenty of fields such as batteries, [ 30 ] supercapacitor, [ 31 ] coating, [ 32 ] biosensors, [ 33 ] filler, [ 34 ] and electromagnetic metamaterials. [ 35 ] The incorporation of GO with MOFs is supposed to change the dispersion stability in great extent and combine the advantages of both parent materials.…”
