Summary: Aqueous zinc-ion batteries (AZIBs) are considered as potential alternatives to lithium-ion batteries (LIBs) due to their safety, convenience, and environmental friendliness. However, the use of vanadium-based compounds as cathodes for AZIBs often leads to dissolution and large volume changes. The pre-insertion strategy of guest ions or molecules provides an effective solution to this problem.

Summary: Rechargeable aqueous zinc-ion batteries (AZIBs) are gaining attention as a promising technology for large-scale stationary energy storage devices due to their inherent safety, cost-effectiveness, eco-friendliness, and acceptable electrochemical performance. Layered manganese/vanadium (Mn/V) oxides, with adjustable interlayer spacing and considerable specific capacity, have attracted interest as cathode materials for AZIBs. However, issues such as slow reaction kinetics, poor electrical conductivity, and dissolution of active materials hinder their full potential. Interlayer engineering with pre-intercalation is considered an effective solution to overcome these challenges.

Summary: The exploration of electromagnetic wave absorbers with anticorrosion for military targets in harsh environments is a challenging task. In this study, core@shell structure Prussian blue analog-derived NiCo@C, CoFe@C, NiFe@C, and NiCoFe@C were obtained with excellent EM wave absorption performance. Among them, NiCoFe@C achieved a minimum reflection loss of -47.6 dB and an effective absorption bandwidth of 5.83 GHz, covering the whole Ku-band. Additionally, these absorbers showed lower corrosion current density and larger polarization resistance under different corrosion conditions, and the salt spray test had little effect on their absorption performance and surface morphologies.

Summary: The construction of heterojunctions between semiconductors and metal-organic frameworks is an effective strategy for improving photocatalytic nitrogen fixation activity. CAU-17 was added during the synthesis of ZnCdS, resulting in the generation of Bi2S3 on the ZnCdS@CAU-17 heterostructures. The combination of the three catalysts leads to enhanced nitrogen fixation performance, attributed to the carrier of CAU-17 for N2 adsorption and storage, the active site of ZnCdS, and the efficient transport of electrons facilitated by Bi2S3. The photocatalytic nitrogen fixation performance of ZCS@CAU-100 is significantly higher compared to pure CAU-17 and ZnCdS. The composite of Bibased MOF and semiconductor provides new insights for the synthesis of more efficient photocatalysts for nitrogen reduction reactions.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
