The implementation of aqueous zinc-ion batteries (AZIBs) in energy storage systems has uneven Zn dendrites and side reactions seriously at the zinc anode and electrolyte interface. A novel green biomass carbon quantum dot (BCDs) additive influenced the hydrogen bonding network of the electrolyte, reduced water activity, and suppressed hydrogen evolution corrosion of the zinc anode. At the same time, we proposed a buffer redistribution effect that BCDs can act as the support of SO, and the linkage mechanism can further prolong the residence time of Zn on SO-BCDs. This effectively allows more time for the adsorbed Zn to migrate to the most stable position on Zn (0 0 2) and form a perfect pattern, it regulated the Zn solvation network and interfacial chemistry of zinc anodes. In addition, the Zn||Zn-symmetric battery with a current density of 1 mA cm/1 mAh cm can cycling 3450 h. And the constructed full Zn||PANI full battery can be stably cycled 5000 cycles at a current density of 0.5 and 5 A g. This study reveals the principle of maximizing zinc utilization solvate structural interface design, and highlights the commercial potential of BCDs additives in the design for efficient and durable AZIBs.

This study aimed to determine the structure-function relationship (SFR) for ChCl-glycerol mixtures, a deep eutectic solvent (DES), by investigating their microscopic solvation dynamics and how it relates to their macroscopic properties across varying concentrations of ChCl. Femtosecond transient absorption (fs-TA) spectroscopy revealed two distinct solvation dynamics time constants: , governed by glycerol-glycerol interactions, and , dominated by the choline response. The minimum at 25-30 mol % ChCl closely aligned with the eutectic composition (~33.

Incompatible electrode/electrolyte interface often leads to dendrite growth, parasitic reactions and corrosion, posing significant challenges to the application of Zn anodes. Herein, we introduce a biomimetic antifreeze protein localized gel electrolyte (ALGE) with multifunctional capabilities to address these issues by combining electrolyte modification with interface optimization. ALGE modifies the Zn2+ solvation structure and the hydrogen-bond network adjacent to zinc anode, effectively suppressing hydrogen evolution.

Zinc-ion batteries become a major research focus in energy storage, valued for their low cost and high safety. However, their widespread application is hindered by poor zinc anode stability caused by dendrites, side reactions, and poor performance across a wide temperature range at a strong hydrogen bond network aqueous electrolyte. In this study, we propose a strategy for the synergistic combination of a polyacrylamide hydrogel with sucrose.
