Lithium argyrodites with high ionic conductivities are favorable solid electrolytes (SEs) for all-solid-state batteries (ASSBs). However, their low preparation efficiency and poor cycling performance hinder their large-scale applications. In this work, we demonstrate successful large-scale production (over 1 kg per batch for the first time) of Li5.5PS4.5Cl0.75Br0.75 (LPSCB) by fast dry mixing followed by annealing, which presents high room temperature ionic conductivities of 13 mS cm−1 for cold-pressed and 25 mS cm−1 for sintered pellets. Combining neutron powder diffraction and 6Li → 7Li tracer-exchange nuclear magnetic resonance (NMR) spectroscopy measurements, we show that intercage jumps frequently occur through the 48h-16e-48h pathway in LPSCB, promoting the overall lithium conduction. The assembled ASSBs using LPSCB and a LiNi0.83Co0.11Mn0.06O2 electrode can be cycled for over 2,500 cycles at a 0.5 C rate and 1,800 cycles at a 2 C rate without any capacity degradation. Our results will accelerate the commercialization of sulfide SE for ASSBs. © 2025 Elsevier Inc.

Radiant heat dissipation has emerged as a critical technique for effective thermal management, offering energy efficiency, cost-effectiveness, and adaptability to various shapes while promoting environmental sustainability. However, the intricate relationship between material structures and emissivity remains inadequately understood. This study primarily utilizes a straightforward and economical solvothermal method to regulate the synthesis of Fe3O4 ferrite, exploring its structural relationship with infrared radiation performance. By adjusting the solvent ratio of ethylene glycol and diethylene glycol in the solvothermal system, we successfully synthesized uniformly dispersed Fe3O4 nanospheres ranging from 10 to 800 nm. Notably, our research revealed a positive correlation between infrared emissivity and the particle size. Submicron hollow spheres with a size of 800 nm exhibit an exceptionally high emissivity of 0.992 within the 8~13 μm wavelength range. Morphological and size variations induced alterations in lattice strain, oxygen vacancies, and phonon lifetimes, which consequently influencing the lattice vibration absorption and infrared emissivity. Moreover, the device surface with a composite coating formed by combining 15wt% Fe3O4 particles with organic matter, achieves a temperature difference of 17.6 °C under a 4 W input power condition compared to blank device. This finding contributes to further revealing the process of material radiative heat dissipation, driving the application of high-emissivity materials for heat dissipation in high-power electronic devices. © 2024, The Authors.

The Ta-N layer on the Ta matrix surface was synthesized using microwave plasma nitriding (MPN) to enhance its wear resistance. The effects of holding time on the phase composition, morphology, mechanical properties, friction, and wear of the nitriding layers were systematically examined. The results revealed that nanocrystalline Ta-N layers with a dense surface and low roughness were successfully fabricated. The thickness of the Ta-N layer increased from 0.87 μm to 4.23 μm with prolonged holding time. The hardness of the Ta-N layer increased first and then decreased with the extension of holding time, and reached the maximum at 4h. Friction and wear test results indicated that the Ta-N layer exhibited superior wear resistance at the holding time of 4 h, which was mainly attributed to the synergy of dense structure and the generation of the nanocrystal. In conclusion, the Ta-N layer with the desired hardness and wear resistance was obtained due to MPN treatment, which offered excellent surface protection for the Ta matrix in terms of wear resistance. © 2024, The Authors.

Structural material parameters such as grain size, texture, and grain boundary species play crucial roles in anisotropic thermoelectric materials. In this study, the underlying mechanism for rational regulation of grain size, texture, and grain boundary species is uncovered. The variations in the plastic deformation capability and the atomic diffusion rates at different extrusion temperatures lead to a competition between dynamic recrystallization (DRX) and grain growth, which allows for quantitative regulation over grain size, texture, and low-angle grain boundaries (LAGBs) in the material. As a result, grain size can be effectively tuned from the nanometer scale to the micrometer scale, with the orientation factor F(110) adjusting from 0.23 to 0.41, and the concentration of LAGBs varying between 10.9% and 25.2%. The sample extruded at 673 K exhibits an average grain size of 800 nm, which contribute to the observed compressive strength of 226 MPa and bending strength of 126 MPa. Additionally, the high texture and high density of LAGBs ensure a high carrier mobility of 247 cm2 V-1 s-1. The ZT value of 1.2 enables micro-TEC modules and conventional TEC modules to achieve maximum temperature differences (ΔTmax) of 60 K and 78 K, respectively, at the hot-side temperature of 300 K. © 2024, The Authors.
