Abstract The lithium–sulfur (Li–S) battery is considered as a promising future energy storage device owing to its high theoretical energy density, low cost of the raw active material (sulfur), and its environmental friendliness. On the other hand, there are still challenging issues for the practical applications of Li–S batteries, including low sulfur utilization, poor cyclability, and rate capability. Although considerable efforts are made to overcome the current obstacles in Li–S batteries, on
A straightforward method for significantly improving the moisture resistance of MOFs is described. In the proposed method, MOFs are subjected to thermal treatment, thus inducing the formation of an amorphous carbon coating on the MOF surfaces that prevents hydrolysis. This approach should open up new practical applications for MOFs in areas hitherto unexplored due to concerns regarding moisture sensitivity.
1T exfoliated MoS<sub>2</sub>@CNT-based bifunctional separators in a tandem configuration delivered excellent electrochemical performance, and rational guidelines for preparing bifunctional separators for lithium sulfur batteries were suggested.
The battery–supercapacitor hybrid electrode, consisting of both faradaic rechargeable battery components and non-faradaic rechargeable supercapacitor components in a single electrode, is successfully developed using Li4Ti5O12–activated carbon (LTO–AC) hybrid nanotubes in a negative electrode for an advanced energy storage device. Li4Ti5O12 and PVA-derived activated carbon are hybridized with morphological control over the one-dimensional (1D) tubular structures via an in situ sol–gel reaction co
Hydrogen is a promising energy carrier that can potentially facilitate a transition from fossil fuels to sustainable energy sources without producing harmful by-products. Prior to realizing a hydrogen economy, however, viable hydrogen storage materials must be developed. Physical adsorption in porous solids provides an opportunity for hydrogen storage under low-stringency conditions. Physically adsorbed hydrogen molecules are weakly bound to a surface and, hence, are easily released. Among the v
In this work, we report the preparation of reduced graphene oxide (rGO)-based freestanding recyclable oil adsorbents via an environmentally friendly one-step low-temperature thermal reduction process. The heating rate was adjusted to successfully control the macroporosity of the rGO films (rGOFs), thereby modulating the adsorption behaviors. The adsorption capacities for a variety of organic solvents and oil species, measured as the percentage weight gain, were measured. Adsorption capacities up
