Summary: In recent years, gel-electrolyte has played a crucial role in various aspects of zinc-ion batteries, such as preventing hydrogen evolution, reducing dendrite growth, and protecting the zinc metal anode. This study introduces a polyvinyl alcohol-based water-organic hybrid gel electrolyte, containing Agar and dimethyl sulfoxide, which enables the spontaneous desaturation of the solvation sheath to reduce hydrogen evolution and dendrite growth at room and low temperatures. Experimental characterization and theoretical calculations confirm the effective binding between the multihydroxy polymer and water in the hybrid desaturated gel-electrolyte, regulating the inner and outer sheath. The hybrid gel-electrolyte exhibits an impressive ionic conductivity of 7.4 mS cm(-1) even at -20 degrees C with a minimal amount of zinc trifluoromethanesulfonate (Zn(OTf)(2)).

Summary: Micro-supercapacitors (MSCs) have significant advantages and have attracted increasing attention. However, in open systems, they often need to be encapsulated to ensure stable performance. In this study, we demonstrate a high water-retaining and antifreeze micro-supercapacitor (AW-MSC) that does not require encapsulation and is adaptable to all-weather conditions. The AW-MSC uses an ion conductive hydrogel as the electrolyte and exhibits outstanding water holding capacity and freeze resistance. In harsh environments, the AW-MSC retains over 85.0% of its capacitance.

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.
