The lithium silicon phosphor sulfo-chloride (LiSiPSCl) with a Li10GeP2S12-type structure is one of the most promising solid electrolytes (SEs) for all-solid-state lithium-ion batteries (ASSLIBs) due to its currently highest ionic conductivity at RT. In this work, three kinds of LiSiPSCl electrolytes, i.e. Li7.59(10)Si1.95(9)P1.65(7)S11.64(1)Cl0.36(1) (SE-450), Li7.67(12)Si1.90(1)P1.67(1)S11.61(2)Cl0.39(2) (SE-475) and Li7.58(5)Si1.75(4)P1.79(2)S11.54(4)Cl0.46(4) (SE-500), were prepared at 450 / 475 / 500 oC for 8 h through a solid-state method. The assembling of blocking / symmetrical / semi-blocking cells and ASSLIBs, and electrochemical measurements were carried out by coupling the three SEs with two kinds of anodes (Li metal and Li-In alloy) and one cathode of LiNbO3-coated LiNi0.8Co0.1Mn0.1O2 (NCM@LNO). Studies were focused on chemical compositions, phase compositions, structure refinements, electrolyte/anode and electrolyte/cathode interfacial stability. Results show that LiSiPSCl electrolytes had favorable interfacial stability with Li-In anode and exhibited low polarization voltage ( © 2023, The Authors. All rights reserved.

Significantly enhanced energy storage performance of BaTiO3-based amorphous thin films through the synergistic function of variable valence ions

Amorphous thin films have been widely studied due to the excellent breakdown strength in recent years. However, their practical application faces significant challenges primarily caused by low polarization and energy density. Herein, we propose a multi-variable valence ions doping strategy to enhance the energy storage performance of BaTiO3-based amorphous thin films. The Ba0.92Bi0.08Ti1-x(Ni0.5Mn0.5)xO3(BBTNM) amorphous thin films were fabricated by chemical solution deposition method. In addition, the synergistic effects of variable valence ions (Ni, Mn) on the microstructure, dielectric and energy storage properties of the films were systematically studied. Compared with the undoped Ba0.92Bi0.08TiO3(BBT) film, the polarization and energy storage performance of the BBTNM film have been significantly improved owing to the defect dipoles generated by the incorporation of variable valence ions. Notably, a high discharge energy density of 93.3 J/cm3 together with an energy efficiency of 83 % could be achieved in the x = 0.08 film at 7.05 MV/cm. Simultaneously, the film exhibits excellent thermal stability within the range of 20 °C–160 °C, and still maintains favorable performance after 105 cycles. Overall, this work introduces a new approach for designing BaTiO3-based thin film materials. © 2025

Microwave absorption(MA) materials have been captured extensive attentions due to the serious electromagnetic(EM) pollution. Numerous interests focus on the MA performances of core-shell structural composites with magnetic constituents as cores and dielectric constituents as shells, which inevitably suppressed the magnetic coupling causing the decrease of magnetic loss to some extent. Herein, the coreshell structural carbon(C) microsphere/magnetic metal composites were fabricated through the combination of an electrostatic assembly approach and subsequent in-situ reduction reaction. The complex permittivity and permeability of core-shell C@magnetic metal composite system can be effective adjusted by the constituent and microstructure of shells. Thanks to the distinct magnetic coupling from the subtle designed structures and the promotion of the magnetic-dielectric synergy, the C@magnetic metal composite exhibited enhanced MA properties. The optimal reflection loss(RL) of C@Ni composite was-54.1 dB with a thickness of 3.4 mm, meanwhile the effective absorbing band could reach over 5.5 GHz at only a1.8 mm thickness. Broad absorption bandwidth with RL below-10 d B could achieve 6.0 GHz and 6.7 GHz for C@Co and C@Ni Co composites with a thin 2.1 mm thickness, respectively. Our exciting findings might lead a guide on the novel structure design for the functional core-shell structural composites used for microwave absorption.
