Summary: The design of composite sulfur cathode is crucial for determining the physical and chemical properties of all-solid-state lithium-sulfur batteries (ASSLSBs), and the selection of solid-state electrolyte in the composite sulfur cathode is rarely studied. By comparing three typical sulfide solid-state electrolytes, the excellent compatibility between Li7P(3)S(11) electrolyte and sulfur cathode is revealed. The ASSLSBs based on Li7P(3)S(11) electrolytes exhibit fast reaction kinetics and high electrochemical stability, contributing to chemical congruency. These findings provide guidance for developing high-energy-density ASSLSBs.

Summary: The electronic structure of single-atom catalysts (SACS) plays a critical role in bifunctional oxygen electrocatalysis. In this study, the electronic structure was effectively adjusted by introducing a heterogenous metal that bonded directly to the active center atom. This adjustment resulted in optimized binding energy and reduced energy barriers for catalytic reactions. Theoretical calculations confirmed these effects and the uniform distribution of 3d orbitals, which improved the bifunctional oxygen electrocatalytic reactivity. The constructed bifunctional catalyst exhibited outstanding electrocatalytic performances in various energy storage systems. The generality and expandability of this strategy were demonstrated by the successful development of other dual-metal catalysts systems with different active metals.

Summary: In this study, the relationship between intrinsic oxygen reduction reaction (ORR) activity and electrochemiluminescence (ECL) behavior was explored using single-atom catalysts (SACs). By combining electrochemical ORR catalyzed via SACs and chemical oxidation of luminol, the traditionally neglected cathodic ECL emission of luminol was significantly enhanced. This work is important for guiding the development of an amplified sensing platform through rational tailoring of the ORR activity of SACs and potential-resolved ECL assays based on high-efficiency cathodic ECL.

Summary: Conventional methods of fabricating antiviral and antibacterial textiles often suffer from degradation after long-term use, as the functional additives on the fabric surface can leach out. In this study, copper ions were impregnated into the cellulose matrix of textiles, forming a copper ion-textile (Cu-IT) that exhibited strong coordination bonding with cellulose chains. The Cu-IT demonstrated high antiviral and antibacterial performance against various viruses and bacteria, and its excellent air/water retainability and mechanical stability made it suitable for daily use and repeated washing.

Summary: Li-metal batteries (LMBs) are attracting research attention again due to their high-energy requirements. Commercial carbonate electrolytes have unfavorable reactions with the Li-metal anode, leading to the formation of unstable solid electrolyte interphase (SEI) and Li dendrites. However, the incorporation of lithium nitrate (LiNO3) into commercial carbonate electrolytes can successfully stabilize the SEI and enable dendrite-free Li-metal anode, making LMBs practical.
