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.

具有最高理论容量的锂金属被认为是下一代高能量密度电池中最有前景的负极,但长循环过程中的锂枝晶生长和负极的体积膨胀阻碍着其实际应用.尽管已有研究使用石墨烯气凝胶等三维主体用于容纳锂金属,但单一的石墨烯气凝胶难以承受充放电过程中负极的大体积变化.因此,本文制备了具有自适应机械弹性的聚酰亚胺纳米纤维互锁多孔石墨烯复合气凝胶(PI-HGCA),将其作为复合主体结构用于容纳锂金属.具有面内纳米孔的多孔石墨烯纳米片可以有效地调节锂离子通量并提供高度定向的离子转移路径.此外,三维复合气凝胶主体由水平排列的多孔石墨烯片层和互锁的聚酰亚胺纳米纤维构成,其在长期循环过程中对负极的体积变化表现出高度可逆的自适应压缩弹性.预锂化的PI-HGCA负极在对称电池中显示出极低的过电势(46 mV),并具有1300次的长循环寿命;其与LiFePO_(4)正极所组装而成的全电池在1 C下经过800次循环后仍然显示出81.2%的超高容量保持率,表明该互锁气凝胶复合结构在高能量密度锂金属电池中具有巨大应用潜力.

Polymer-based dielectrics have attracted much attention in the field of flexible electronics due to their excellent flexibility, dielectric and mechanical properties. However, the rational design of nanofiller-polymer nanocomposite for improving dielectric and mechanical properties remains challenging. Herein, layered nanocomposites filled with high-κ Ca2Nb3O10 perovskite nanosheets were fabricated via shear-flow induced alignment of nanosheets. The hierarchical structure and good dispersion of nanosheets endowed the layered nanocomposites with an outstanding modulus of 12.7 GPa and toughness of 1.8 MJ/m3. Meanwhile, the layered nanocomposites exhibited a high dielectric constant of 14.7, a low dielectric loss of 4.2%, and low leakage current density -7 A/cm2. The layered high-κ nanocomposites designed in this work will have broad application prospects in th flexible electronics. © 2024, The Authors. All rights reserved.

The construction of Mn carbon-based composite/PMS systems with structured active sites is an effective strategy for organic conversion. However, the complex structure of the composite catalyst/PMS systems has hindered the exploration of the origin and generation stages of active species. This paper investigates the correlation between C=O-Mn and reactive species generation by developing Mn carbon composites with structured active sites (C=O) to activate PMS for the degradation of TCH. Additionally, a pre-oxidation experiment was proposed to divide the whole catalytic degradation process into two stages: oxidation and degradation. The results show that the C=O-Mn-PMS composite intermediate can still effectively degrade Tetracycline after being separated from the solution. The study also revealed the structure-function relationship of different active sites in the C=O-Mn catalyst was revealed by density functional theory (DFT) calculations. The Mn-O, Mn-O-Mn and C=O structures achieved efficient utilization of PMS and rapid degradation of TCH through the adsorption of PMS and single electron transfer generation SO4•–, •OH, O2•–, 1O2. This paper provides new ideas for the reaction mechanism and rational design of catalysts based on the Mn-carbon composite/PMS system. © 2023, The Authors. All rights reserved.
