The development of compact Lithium-Sulfur (Li-S) batteries with improved performances is becoming one of the most desirable aspects of future energy technologies. Beyond Li-ion batteries, Li-S is of high importance to follow that adapts to the specificity of each application. It is one of the best candidates for high-performance energy storage systems due to its large theoretical capacity (1674 mAhg–1)

The fullerene acceptor, which has historically been used in bulk-heterojunction (BHJ) organic solar cells, is being replaced by non-fullerene acceptors due to its problem of high energy loss (Eloss). To reduce the energy loss in BHJ organic solar cells as a means to improve open-circuit voltage (Voc), several approaches have been applied to diminish recombination loss, notably enhancements to film

ABSTRACT. Metal organic frameworks (MOFs) have received considerable importance as proton conducting materials in recent times. However, most of the MOFs lack the ability to form film, which limits their application. In the present work, polybenzimidazole (PBI) composite membranes have been prepared by loading post synthetically modified (PSM) UiO-66-NH2 MOFs, denoted as PSM 1 and PSM 2 into the arylether-type

The appropriate exploitation of the plentiful recycled Pb from discarded lead-acid batteries is both challenging and profitable, which can alleviate lead pollution and take advantage of potential Pb resource. The Pb with high theoretical capacity (569 mAh g-1), excellent electrical conductivity, low price, and high safety demonstrates great potential as anode for lithium-ions batteries (LIBs). Herein

Smart glass offers dynamic control over the transmission of light to address various needs in energy conservation, privacy, and information display; yet, most of the existing technologies still require continuous power for operation and are limited to single functions (usually either tint or haze control). In this work, we have developed a versatile tristable smart glass based on cholesteric liquid

Gas storage via adsorption in microporous crystals, such as zeolites, has the potential to transform both the energy and transportation sectors. This potential results from the highly tunable pore chemistry and geometry of zeolites, which allows for precise control of the chemical environment of the adsorbed gas. However, while strong gas-solid inter-actions are desirable to maximize gas storage capacity

Detailed atomistic understanding of the vanadium redox reactions taking place at electrode/water interfaces is key for improvement of the power density of vanadium redox flow batteries. In this work, we employ \textit{ab initio} molecular dynamics based metadynamics simulations to examine V$^{2+}$/V$^{3+}$ and VO$_2^{+}$/VO$^{2+}$ redox reactions at the oxygen functionalized graphite (11$\overline{2}$0)

Designing composite electrodes with optimal microstructure, composition, and choice of active material (AM) as well as solid electrolyte (SE) is critically important for the development of high-performance solid-state batteries (SSBs). To optimize AM loading that includes loading amount, composition, dispersion state and maximize AM utilization in composite SSB electrodes, we need to precisely understand

The original Figure 1f and its corresponding caption for panel f do not match. The panel f caption described the water oxidation of Si/NiO with a band diagram, while the figure appeared to be the XRD spectra. Therefore, Figure 1 has been modified, which is the “band diagram of Si/NiO photoanode for water oxidation reaction”. The figure modification was not reflected at the time of revision. Fortunately

Porous noble metal aerogels have emerged as an attractive target in scientific community owing to their diverse applications. Nonetheless, their formation and development still faces vital problems such as complexity and long gelation time. In this manuscript, we report a facile, one-pot and short gelation time strategy for making a Pd-Au aerogel consisting of extended metal backbones by using a self-assembly

Three-dimensional (3D) gas diffusion electrodes (GDEs) as support for catalytic nanoparticles are important to the electrolysis and fuel cells fields to facilitate reactant transport and distribution, and reach higher current densities. Hence, the assembly of nanostructured catalytic particles directly onto GDEs during the synthesis could be a powerful one-step strategy to target high performance and

With a motivation to discover efficient materials for direct electrolysis of seawater, bi-metallic oxy-boride (Co-Fe-O-B) nanostructures were developed using a facile hydrothermal synthesis strategy, with varying content of Fe. The oxygen evolution performance of the optimized Co-Fe-O-B catalyst in alkali water (1 M KOH), showed higher reaction rates owing to a Co3O4-core-Co2B-shell structure, which

Two-step synthesis method involving electrodeposition of Bi precursor and drop-casting V precursor is widely used to produce highly efficient BiVO4 photoanodes. This method requires a final etching step to remove excess V2O5 on top of BiVO4 and the use of chemical etching with aqueous NaOH solution is the most common. However, there is an issue with uniformity and reproducibility of BiVO4 due to local

The performance of platinum group metal (PGM)-free bifunctional electrodes, in a regenerative H2/O2 micro-fluidic cell, is examined. The system is operated in alkaline environment at 25 °C. Multiwalled carbon nanotubes (CNT) supported Ni-based nanostructures, NiO-Ni/CNT, were used to catalyze the hydrogen evolution reaction (HER) and the hydrogen oxidation reaction (HOR); whereas N-doped carbon nanohorns

Li metal is considered as an ideal anode material for next-generation high energy density batteries. However, the huge volume change during cycling and uncontrollable Li dendrites growth represent the main issues of a Li metal anode such as short lifespan, low coulombic efficiency and serious safety risks.

To meet the requirement for the high-ranked positive electrode materials having auspicious pseudocapacitive features for potential application in energy storage devices, the suitable designs of unique core-shell heterostructures featuring mixed transition metal oxide and layered double hydroxide (LDH) are highly needed and progressing expeditiously in recent years. Herein, 3D hierarchical zinc-nickel-cobalt

In chloroaluminate ion based aluminum-ion batteries, a graphite cathode shows promising electrochemical performance. However, its low capacity and high volume expansion is a major hindrance. This is due to the limited intercalation of the AlCl4- ion into the graphite layers. As a possible solution to this, graphdiyne (GDY) and hydrogen-substituted graphdiyne (HsGDY), two-dimensional carbon allotropes

There is an urge to develop new hole transporting materials (HTMs) for perov¬skite solar cells (PSCs), which can yield comparable power conversion efficiencies (PCEs) yet mitigate the issue of stability associated with the state-of-the-art HTM spiro-MeOTAD. Here¬in, we designed and prepared C2v-symmetric spiro-configured HTM-1 comprising a central acridine-cyclopentadithiophene core unit flanked with

Surface modification through Li3PO4 (LPO) coating is a brilliant approach to inhibit oxygen release of Ni-rich layered Li[Ni0.8Co0.1Mn0.1]O2 (NCM811) cathodes, particularly under highly delithiated states, which can help tackle the thermal runaway issue for industrial applications. While the mechanism of LPO prohibiting the release of the oxygen from the surface of NCM811 is still unclear. Herein we

High rate storage of sodium ions in lithium titanate still keep unsolved, although the sodium as medium in materials can reduce the voltage platform and enhance the high energy density of electrochemical batteries. Herein, the composite lithium titanate/carbon nanotubes materials are synthesized to improve the kinetics process by designing pathways to migrate the electrons and ions. Special micro-nano

Two indaceno[1,2-b:5,6-b’]difuran-based non-fullerene acceptors (NFAs) IDF-IC and IDF-4F were designed and synthesized. IDF-IC and IDF-4F showed strong absorption in the visible and near-infrared (NIR) region with narrow bandgaps of 1.56-1.62eV. The power conversion efficiency (PCEs) of PM6:IDF-IC and PM6:IDF-4F devices were 7.80% and 7.81%, respectively, with open-circuit voltages (Vocs) of 0.905

We design a new type of heterostructured MnO2@SnO2 hollow spheres composite. The particular hollow heterostructured structure materials contain two parts, one is the MnO2 hollow spheres and the other is the SnO2 scattered nanoparticles on the surface of MnO2 hollow spheres. The MnO2 hollow spheres are the composites “skeletons”, and the SnO2 scattered nanoparticles are the “muscle”. MnO2 hollow spheres
