Organic cathode materials have garnered significant attention for their potential application in lithium-ion batteries due to their lightweight nature, tunable structures, high energy density, and environmental friendliness. However, the dissolution of organic cathodes in liquid electrolytes often leads to poor cycling stability, which limits their practical application. In this study, a composite cathode was prepared by ball milling the PTCDA/CuS (perylene-3,4,9,10-tetracarboxylic dianhydride, PTCDA) with a sulfide-based electrolyte and carbon nanotubes. By optimizing the component ratios, the assembled all-solid-state batteries (ASSBs) show a high discharge capacity of 210 mA⸱h/g after 200 cycles without any capacity degradation at a current density of 33.0 mA/g. Through comprehensive characterization techniques including X-ray diffraction (XRD), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS), the coordination of Cu 2+ and the formation of sulfur-linked polymers during the charge-discharge processes are elucidated, and the reversibility of the electrochemical reactions has been confirmed. This work highlights the excellent compatibility between organic cathodes and sulfide-based electrolytes, providing a new way for the development of high-performance ASSBs with high energy density and extended lifespan.

The physical field in halide chemical vapour deposition film growth is strongly affected by the structure of the reaction chamber. Notably, a highly uniform film thickness can be achieved by optimising this chamber. Therefore, after modelling a reactor, computational fluid dynamics was used in this study to measure temperatures and verify the accuracy of simulations. Based on changes in the substrate surface concentration and temperature, the feasibility of optimising the size and position of the baffle and the inclination angle of the spray holes was studied. The results revealed that on increasing the diameter of the baffle gradually, the uniformity of the substrate surface initially increased and then decreased. The most critical influence of the baffle position is the amount of gas on the substrate surface. As the inclination angle of the spray holes increased, the concentration at the centre of the substrate surface decreased, whereas that at the edge of the substrate increased. Meanwhile, the temperature field remained uniform after optimization. This study demonstrates that the showerhead and baffle can improve the physical field and that it is feasible to optimise the structure by analysing the physical field. © 2022, The Authors.

The ZnO-Ce2O3 composite coating developed in this study significantly enhances the medical applicability of 316L stainless steel by synergistically improving corrosion resistance and antibacterial performance. Through magnetron sputtering, the ZnO-Ce2O3 composite coating reduces the corrosion current density of 316L stainless steel by an order of magnitude (from 2.935 × 10−7 to 1.278 × 10−8 A/cm2), outperforming individual ZnO or CeO2 coatings. Biological experiments demonstrated that the composite coating achieved over 98% antibacterial efficiency against Staphylococcus aureus while exhibiting low cytotoxicity toward mesenchymal stem cells, thereby addressing critical limitations of traditional stainless steel in medical devices. Additionally, the increased water contact angle (from 80° to 114°) correlated with inhibited bacterial adhesion, suggesting a dual antibacterial mechanism. This multifunctional coating strategy offers a promising solution for improving implant safety and patient outcomes. © 2025 Author(s).

To improve electrical properties of BaTiO3 piezoelectric ceramics fabricated by 3D printing, effects of particle sizes was investigated on rheological and curing properties of ceramic slurries, electrical properties of BaTiO3 fabricated by Digital Light processing 3D printing method. It was found that the curing ability of ceramic slurries decreased first and then increased with the increase of particle size from 136 nm to 1486 nm, while the viscosity of the slurries kept decreasing. When the particle size in a range of submicron, the grain size of sintered ceramics decreased from 13.27 μm to 6.84 μm as particle size increasing. Immediately, the relative density, piezoelectric constant, relative permittivity and remanent polarization of sintered ceramics were measured and it turns out to reach 95.32%, 161.4 pC/N, 1512 and 7.59 uC/cm2 respectively while using the BaTiO3 powder with particle sizes of 993 nm. Finally, a cellular structural BaTiO3 ceramics was fabricated by using optimized powder and process parameters and packaged as a piezoelectric sensor, showing a good function of force-electricity conversion. These results demonstrated the feasibility of fabricating high-quality functional ceramics with designed geometry by Digital Light processing. © 2021, CC BY.

Effect of Graphene Surface Functional Groups on the Mechanical Property of PMMA Microcellular Composite Foams

引用

Journal of Wuhan University of technology(materials Science) 2019年第3期34卷 717-722页

The functional groups on graphene sheets surface affect their dispersion and interfacial adhesion in polymer matrix. We compared the mechanical property of polymethymethacrylate（PMMA） microcellular foams reinforced with graphene oxide（GO） and reduced graphene oxide（RGO） to investigate this influence of functional groups. RGO sheets were fabricated by solvent thermal reduction in DMF medium. UV-Vis, FT-IR and XPS analyses indicate the difference of oxygen-containing groups on GO and RGO sheets surface. The observation of SEM illustrates that the addition of a smaller number of GO or RGO sheets causes a fine cellular structure of PMMA foams with a higher cell density(about 1011 cells/cm3) and smaller cell sizes（about 1-2 μm） owing to their remarkable heterogeneous nucleation effect. Compared to GO reinforced foams, the RGO/PMMA foams own lower cell density and bigger cell size in their microstructure, and their compressive strength is lower even when the reinforcement contents are the same and the foam bulk density is higher. These results indicate that the oxygen-containing groups on GO sheets’ surface are beneficial to adhere CO2 to realize a larger nucleation rate, and their strong interaction with PMMA matrix improves the mechanical property of PMMA foams.

Definitions of Pseudocapacitive materials: A Brief Review

引用

Energy & Environmental materials 2019年第1期2卷 30-37页

Pseudocapacitive materials generally offer both high capacitance and high rate capability, which has stimulated great efforts in developing the materials system and related energy storage devices. In recent years, however, with the extensive use of nanomaterials in batteries, fast redox kinetics comparable to pseudocapacitive have been achieved in many kinds of battery materials due to the much shortened ion diffusion lengths and highly exposed surface/interface as a result of nanosize effect. Consequently, the terms"pseudocapacitive materials" and "battery materials" are becoming more and more confusing. In this review, different opinions on the definition of pseudocapacitive materials and the evolution of the definitions as well as the resulting confusion will be firstly reviewed. Then, to accurately distinguish pseudocapacitive and battery materials, method with the consideration of both the electrochemical signatures(CVs and GCD) and quantitative kinetics analysis as a supplement is proposed. Finally, we end this review by discussing the possible device configurations of asymmetric supercapacitors and hybrid supercapacitors. The present review will help understanding the differences between pseudocapacitive materials and battery materials, and thus avoiding the definition confusion.

Magnesium batteries are promising post-lithium storms for their low cost and high energy density. Engineering novel cathodic materials compensates the charge imbalance due to the introduction of the bivalent magnesium cation in the framework of the cathode is one of the key solutions for realizing practical Mg battery. Herein, crystal engineering of WS2 using Al doping strategy are conducted to regulate magnesium storage and electrochemical reaction kinetics of WS2 cathodes. tungsten disulfide (WS2) and Al-doped WS2 (WS2@Alx, x=0, 2 and 4 wt.%) are prepared by a one-step hydrothermal technique and used as a cathode material for magnesium batteries. We explore the Mg2+ insertion/extraction process on the WS2@Alx in the presence of halogen free electrolyte (HFE) based on 0.69 M Mg(NO3)2·6H2O dissolved in acetonitrile (ACN):tetra ethylene glycol dimethyl ether (G4) (∼2: 1). The Mg/WS2 full battery containing Al delivered high initial discharge capacity compared with the Al free cell. The introduction of anode/electrolyte polymer interface inhibits the passivation of Mg anode, via insulation between the liquid electrolyte and Mg anode. This study provides an effective method to design a practical Mg cathode and a new understanding of crystal engineering of WS2 by Al doping which may help in constructing high performance cathode for Mg batteries applications. © 2023, The Authors.
