The effect of nanoscale confinement of a salt on its ionic conductivity was studied for [NEt4][TFSI] melt-loaded in three isoreticular zirconium-based MOFs: UiO-66, UiO-67, and PCN-56. Conductivity of the MOF-salt composites was up to a factor of 50 higher than the pure salt, and maximized with slightly less than full loading of the MOFs.

Poly(ethylene oxide) (PEO) has been widely studied as an electrolyte owing to its excellent lithium compatibility and good film-forming properties. However, its electrochemical performance at room temperature remains a significant challenge due to its low ionic conductivity, narrow electrochemical window, and continuous decomposition. Herein, we prepare a multifunctional polar polymer to optimize PEO's electrochemical properties and cycling stability.

ConspectusThe advancement of synthetic methodologies is fundamentally driven by a deeper understanding of the structure-reactivity relationships of reactive key intermediates. Carbyne anions are compounds featuring a monovalent anionic carbon possessing four nonbonding valence electrons, which were historically confined to theoretical constructs or observed solely within the environment of gas-phase studies. These species possess potential for applications across diverse domains of synthetic chemistry and ancillary fields.

Hydrogel electrolytes are crucial for solving the problems of random zinc dendrite growth, hydrogen evolution reactions, and uncontrollable passivation. However, their complex fabrication processes pose challenges to achieving large-scale production with excellent mechanical properties required to withstand multiple cycles of mechanical loads while maintaining high electrochemical performance needed for the new-generation flexible zinc-ion batteries. Herein, we present a superspreading-based strategy to produce robust hydrogel electrolytes consisting of polyvinyl alcohol, sodium alginate and sodium acetate.
