Summary: Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition. Based on underpotential deposition (UPD), an escort effect of electrolyte additives for uniform Zn deposition at the atomic level is proposed. With nickel ion (Ni2+) additives, metallic Ni deposits preferentially and triggers the UPD of Zn on Ni, facilitating firm nucleation and uniform growth of Zn while suppressing side reactions. The optimized cell operates for over 900 h at 1 mA cm(-2), more than 4 times longer than the blank one, indicating the significance of this work.

Summary: This study introduces a polyanionic strategy by developing a hydrogel electrolyte with carboxyl groups, to improve the reversibility and performance of aqueous Zn-ion energy storage systems. The carboxyl groups in the hydrogel structure promote the transport of Zn2+ ions and expedite their desolvation, leading to enhanced deposition kinetics. These functional groups also suppress dendritic growth and side reactions, resulting in a smooth surface texture of the Zn anode. The electrolyte exhibits high Coulombic efficiency and exceptional cyclability, making it suitable for energy storage in flexible, intelligent electronics.

Summary: In this study, a novel deep eutectic solvent electrolyte containing choline chloride (ChCl) and ZnCl2 was developed to improve the cycle life of aqueous Zn metal batteries (ZMBs). ChCl coordinates with Zn2+ to reduce water activity and mitigate cathode dissolution and zinc dendrite formation. With this electrolyte, the vanadium oxide cathode maintains a high capacity over 100 cycles at a harsh current density, and the Zn metal anode can be cycled for a longer time without dendrite formation. The results highlight the importance of ChCl as a co-solvent for ZnCl2 in facilitating high performance of ZMBs.

Summary: Aqueous zinc ion batteries (AZIBs) are gaining increasing attention for large-scale energy storage systems due to their safety, low cost, and scalability. Unfortunately, the use of zinc metal anode in AZIBs is hindered by side reactions, dendrite growth, and hydrogen evolution. In this study, the introduction of trifunctional tranexamic acid (TXA) into the electrolyte is proposed to enhance the anode/electrolyte interface and regulate the solvation structure of zinc ions. The experimental and simulation results demonstrate the crucial role of TXA in controlling the anode interface chemistry and electrolyte environment, leading to improved performance and stability of AZIBs.

Summary: Increasing the cutoff charge voltage of LiCoO2 (LCO) poses a challenge in balancing high energy density and long cycling life. By adding 2,3-dimethylmaleic anhydride (DMMA) as an electrolyte additive, a stable and robust CEI film enriched with inorganic species is formed, preventing decomposition of electrolytes and erosion of LCO. Experimental techniques combined with theoretical calculations reveal the functioning mechanism. The addition of DMMA improves LCO's capacity retention after cycles, and the presence of other additives further enhances LCO's high-voltage stability.

Summary: Building 3D electron-conducting scaffolds is an effective way to alleviate dendritic growth and volume change of sodium (Na) metal anodes. A uniform Na plating on the 3D scaffold is achieved by synthesizing NiF2 hollow nanobowls grown on nickel foam (NiF2@NF), which can be electrochemically converted to a NaF-enriched SEI layer. The NaF-enriched SEI layer enables rapid Na(+) transfer throughout the entire 3D scaffold, resulting in densely filled and dendrite-free Na metal anodes.

Summary: Modulating functional groups on molecules can achieve novel electron transport properties in single-molecule electronics. In this work, viologen derivatives with three attached organic radicals including sp2 hybridized O•, NH•, and CH2• are studied for their spin transport properties. The results show excellent spin filtering efficiency (SFE) with α spin conductance being about 100 times larger than β spin conductance within a low-bias window. The findings also demonstrate the tunability of SFE by altering alkyl chain length and applied bias, providing a new strategy for developing viologen-based radical systems as single-molecule spin switches.

Summary: Polymeric conducting binders have significant research value as they can serve as both binders and conducting agents, increasing the proportion of active materials in batteries and the volumetric energy density. This study explores the potential of a composite of PEDOT:PSS and polyethylene glycol (PEG) as a high-performing binder for silicon anodes. The addition of PEG polymer enhances the conductivity of PEDOT:PSS and improves the mechanical properties of the silicon anode, resulting in extended cycle endurance. The use of operando optical microscopy allows for direct observation of the binder's operation. Consequently, the bifunctional PEDOT:PSS/PEG binder shows promise for high-performance lithium-ion battery binders.
