In recent years, research in lithium-ion batteries (LIBs) has been focused on improving their performance various ways, such as density, capacity, and lifetime, but little attention paid to the energy consumption cost manufacturing process. Herein, we report an energy-efficient preparation method of anode materials for LIBs based a self-powered electrospinning system without external power source, which consists rotatory triboelectric nanogenerator (r-TENG), management circuit, unit. By...
Lithium-ion batteries (LIBs) are still facing safety problems, mainly due to dendrite growth on the anode that leads combustion and explosion. Forming a stable solid electrolyte interface (SEI) layer is an effective way suppress this. To induce formation of SEI using simple methods at low cost, we report ultrathin large-scale hexagonal boron nitride (h-BN)/polyimide (PI) was coated commercial polypropylene (PP) separator. The stabilized component induced by h-BN coating proposed, as...
A 2D/3D heterostructure was formed based on inorganic CsPbI<sub>2</sub>Br perovskite, contributing to a high efficiency device with enhanced stability.
Black perovskite-phase cesium lead tri-iodide (CsPbI3) has shown great potential in photochemical applications. However, colloidal CsPbI3 still suffers from the existence of ligands attached to surface nanocrystals (NCs) and serious photoluminescence (PL) quenching. Here, we develop two different γ-phase (γ-CsPbI3) NCs/WS2 heterostructures with two-dimensional morphologies WS2 (nanoplates few-layered nanosheets) improve photocatalytic property γ-CsPbI3 NCs. The large area presence abundant...
Abstract This manuscript describes a straightforward method to prepare stimuli‐responsive fibers by the combined technology of electrospinning and two facile thiol‐ene click chemistry processes: photo‐initialized radical addition thiol‐Michael nucleophilic addition. By controlling molar ratio poly((3‐mercaptopropyl)methylsiloxane) (PMMS) cross‐linker, triallyl cyanurate, PMMS‐based can be partially photo‐crosslinked via UV illumination during electrospinning, grant them solvent‐resistant...
An approach to construct ionic channels in SICSPEs by blending pre-assembled nanowires and hyperbranched polymers for high lithium-ion conductivity.
An <italic>in situ</italic> solution growth method to prepare preferentially assembled and well-distributed α-CsPbI<sub>3</sub> nanocrystals/reduced graphene oxide heterostructures is presented.
Metal‐halide perovskite solar cells (PSC) have shown great success in achieving high efficiencies but less satisfaction long‐term stability. Perovskites are prone to forming hydrates humid environments, which leads the decomposition of materials. Herein, a common and cheap dye molecule, called cis‐di(thiocyanato)bis(2,2‐bipyridyl4,4‐dicarboxylate)ruthenium(II), denoted as N719, is introduced into mixed‐cation mixed‐halide perovskites for better moisture It discovered that N719 molecules form...
Graphene quantum dots (GQDs) have shown great potential in physical–chemical-biological applications, especially for fluorescence monitoring. However, the low activity, safety issues, and unclear synthesis mechanism restrict their application. Here, we investigate process of B,N-GQDs by oxidizing 3-aminophenylboronic acid monohydrate study core parameters (synthesis temperature, H2O2 additional volume, time) corresponding synergic/antagonistic effects a multidimensional wide-ranging region....
Moiré technique is a powerful, important and effective tool for scientific research, from the nano-scale to macro-scale, which essentially interference between two or more periodic structures with similar frequency. In this study, an inverse transmission electron microscopy (TEM) nano-Moiré method has been proposed, first time, reconstruct invisible lattice structure near grain interface, where only one kind of fringe were visible in high resolution TEM (HRTEM) image simultaneously. The...
The variation of the active element on rGO leads to stress state change γ-CsPbI<sub>3</sub> NCs, improving their phase stability.
Metal-organic frameworks (MOFs) with the aggregation-induced emission (AIE) activities exhibit potential applications in fields of energy and biomedical technology. However, controllable synthesis MOFs varied particle sizes not only affects their AIE activities, but also restricts application scenarios. In this work, Eu-MOFs are synthesized by adjusting process parameters, variation rules combining single factor analysis method machine learning technology studied. Based on R2 score, gradient...
Gamma-phase cesium lead tri-bromide perovskite nanocrystals (γ-CsPbBr3 NCs) possess potentially photo-catalytic degradation ability and long-term stability. However, their serious aggregation issue decreases active surface area, the recombination of photo-generated hole–electron pairs weakens property. Furthermore, these NCs can be easily absorbed on dyes [e.g., methylene blue (MB)] or dissolved in dye solution during process, thus reducing amount γ-CsPbBr3 ability. Besides, residual...
