Thermoelectric Power Generation
In article number 2403020, Gang Pei, Bin Zhao, Chongwen Zou, and co‐workers present an innovative all‐day power generation strategy that adaptively integrates diurnal photothermal and nocturnal radiative cooling processes into the thermoelectric generator via a spectrally dynamically modulated coating, which opens up new possibilities for continuous power supply during...
Energy conversion from the environment into electricity is the most direct and effective electricity source to sustainably power off‐grid electronics, once the electricity requirement exceeds the capability of traditional centralized power supply systems. Normally photovoltaic cells have enabled distributed power generation during the day, but do not work at night. Thus, efficient electricity generation...
The industrialization of lithium–sulfur (Li–S) batteries faces challenges due to the shuttling effect of lithium polysulfides (LiPSs) and the growth of lithium dendrites. To address these issues, a simple and scalable method is proposed to synthesize 2D membranes comprising a single layer of cubic graphitic cages encased with few‐layer, curved MoS2. The distinctive 2D architecture is achieved by confining...
The fabrication of perovskite single crystal‐based optoelectronics with improved performance is largely hindered by limited processing techniques. Particularly, the local halide composition manipulation, which dominates the bandgap and thus the formation of heterostructures and emission of multiple‐wavelength light, is realized via prevalent liquid‐ or gas‐phase anion exchange with the utilization...
Mn2+/MnO2 aqueous battery is a promising candidate for large‐scale energy storage owing to its feature of low‐cost and abundant crustal reserves. However, the inherent MnO2 shedding issue results in a limited areal capacity and poor cycling life, which prohibits its further commercialization. In this manuscript, it is revealed that the cause of shedding is the cracking of MnO2 layer due to stress...
Prussian blue analogues (PBAs) have emerged as highly promising cathode materials for sodium‐ion batteries (SIBs) due to their affordability, facile synthesis, porous framework, and high theoretical capacity. Despite their considerable potential, practical applications of PBAs face significant challenges that limit their performance. This review offers a comprehensive retrospective analysis of PBAs'...
Natural polyphenolic compounds play a vital role in nature and are widely utilized as building blocks in the fabrication of emerging functional nanomaterials. Although diverse fabrication methodologies are developed in recent years, the challenges of purification, uncontrollable reaction processes and additional additives persist. Herein, a modular and facile methodology is reported toward the fabrication...
Fabrication of nanozyme with catecholase‐like catalytic activity faces the great challenge of merging outstanding activity with low cost as well as simple, rapid, and low‐energy‐consumed production, restricting its industrial applications. Herein, an inexpensive yet robust nanozyme (i.e., DT‐Cu) via simple one‐step coordination between diaminotriazole (DT) and CuSO4 within 1 h in water at room temperature...
Anodes with high capacity and long lifespan play an important role in the advanced batteries. However, none of the existing anodes can meet these two requirements simultaneously. Lithium (Li)–graphite composite anode presents great potential in balancing these two requirements. Herein, the working mechanism of Li–graphite composite anode is comprehensively investigated. The capacity decay features...
The as‐reported doping entropy engineering of electrode materials that are usually realized by the sharing of multiple metal elements with the metal element from the lattice body, potentially has three shortages of stringent synthesis conditions, large active element loss, and serious lattice distortion. Herein, an interlayer entropy engineering of layered oxide cathodes is proposed, where the multiple...
Ultrathin carbon nitride pioneered a paradigm that facilitates effective charge separation and acceleration of rapid charge migration. Nevertheless, the dissociation process confronts a disruption owing to the proclivity of carbon nitride to reaggregate, thereby impeding the optimal utilization of active sites. In response to this exigency, the adoption of a synthesis methodology featuring alkaline...
Single‐network hydrogels are often too fragile to withstand mechanical loading, whereas double‐network hydrogels typically exhibit significant hysteresis during cyclic stretching‐releasing process due to the presence of a sacrificial network. Consequently, it is a considerable challenge for designing hydrogels that are both low in hysteresis and high in toughness for applications requiring dynamic...
Transparent flexible energy storage devices are limited by the trade‐off among flexibility, transparency, and charge storage capability of their electrode materials. Conductive polymers are intrinsically flexible, but limited by small capacitance. Pseudocapacitive MXene provides high capacitance, yet their opaque and brittle nature hinders their flexibility and transparency. Herein, the development...
Cu2ZnSn (S,Se)4 (CZTSSe), a promising absorption material for thin‐film solar cells, still falls short of reaching the balance limit efficiency due to the presence of various defects and high defect concentration in the thin film. During the high‐temperature selenization process of CZTSSe, the diffusion of various elements and chemical reactions significantly influence defect formation. In this study,...
Interface passivation is a key method for improving the efficiency of perovskite solar cells, and 2D/3D perovskite heterojunction is the mainstream passivation strategy. However, the passivation layer also produces a new interface between 2D perovskite and fullerene (C60), and the properties of this interface have received little attention before. Here, the underlying properties of the 2D perovskite/C...
The increasing need for energy storage devices with high energy density has led to significant interest in Li‐metal batteries (LMBs). However, the use of commercial electrolytes in LMBs is problematic due to their flammability, inadequate performance at low temperatures, and tendency to promote the growth of lithium dendrites and other flaws. This study introduces a localized high‐concentration electrolyte...
Quantum dots (QDs) colloidal nanocrystals are attracting enduring interest by scientific communities for solar energy conversion due to generic physicochemical merits including substantial light absorption coefficient, quantum confinement effect, enriched catalytically active sites, and tunable electronic structure. However, photo‐induced charge carriers of QDs suffer from ultra‐short charge lifespan...
Capillary metal tubes have attracted considerable interest for flexible electronics, portable devices, trace sampling, and detection. Tailoring the microstructure and wettability inside the capillary tubes is of paramount importance, yet it presents great difficulty because of the spatial confinement. Here, the coupling effect is revealed between the fluidic and electric field induced by bubble motion...
Renewable energy technologies, such as water splitting, heavily depend on the oxygen evolution reaction (OER).
