Aqueous zinc-ion batteries have drawn increasing attention due to the intrinsic safety, cost-effectiveness and high energy density. However, parasitic reactions non-uniform dendrite growth on Zn anode side impede their application. Herein, a multifunctional additive, ammonium dihydrogen phosphate (NHP), is introduced regulate uniform zinc deposition suppress reactions. The results show that NH
A hydrated deep eutectic electrolyte with a water-deficient solvation structure and reduced free water in bulk solution is proposed, resulting highly reversible stable Zn anodes.
Although their cost-effectiveness and intrinsic safety, aqueous zinc-ion batteries suffer from notorious side reactions including hydrogen evolution reaction, Zn corrosion passivation, dendrite formation on the anode. Despite numerous strategies to alleviate these have been demonstrated, they can only provide limited performance improvement a single aspect. Herein, triple-functional additive with trace amounts, ammonium hydroxide, was demonstrated comprehensively protect zinc anodes. The...
Aqueous zinc-ion batteries (AZIBs) have experienced a rapid surge in popularity, as evident from the extensive research with over 30 000 articles published past 5 years. Previous studies on AZIBs showcased impressive long-cycle stability at high current densities, achieving thousands or tens of cycles. However, practical low densities (<1C) is restricted to merely 50-100 cycles due intensified cathode dissolution. This genuine limitation poses considerable challenge their transition...

Competition from hydrogen/oxygen evolution reactions and low solubility of N2 in aqueous systems limited the selectivity activity on nitrogen fixation reaction. Herein, we design an aerobic-hydrophobic Janus structure by introducing fluorinated modification porous carbon nanofibers embedded with partially carbonized iron heterojunctions (Fe3 C/Fe@PCNF-F). The simulations prove that can keep internal Fe3 C/Fe@PCNF-F away water infiltration endow a molecular-concentrating effect, suppressing...

Lithium metal anodes (LMAs) have been considered the ultimate anode materials for next-generation batteries. However, uncontrollable lithium dendrite growth and huge volume expansion that can occur during charge discharge seriously hinder practical application of LMAs. Metal–organic framework (MOF) materials, which possess merits specific surface area, excellent porosity, flexible composition/structure tunability, demonstrated great potential resolving both these issues. This article first...
