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: 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: This study introduces a novel interface stabilizer, 2,3,4,5-tetrahydrothiophene-1,1-dioxide (TD), in the 3 m ZnSO4 electrolyte for zinc batteries. The adsorption of TD molecules on Zn surface inhibits the spontaneous chemical corrosions and ensures a homogeneous electrode surface. The stable solid-electrolyte interface (SEI) induced by the adsorbed TD further suppresses parasitic reactions and leads to uniform Zn deposition.

Summary: The study proposes the use of 1,4,5,8-naphthalene diimide (NDI) layered molecules as cathode candidate for ZBs, characterized by sufficient interconnection of nano-particles for continuous electron transport and porous network for facilitated ion filtration. This enables reversible redox of carbonyl function groups with a stable gravimetric capacity around 200 mAh g(-1). Superior cycling and rate performance, benefiting from electrolyte formulation, is achieved with at least 5000 cycles under 3 A g(-1).

Summary: In this study, a CoSe2/Fe3C composite derived from Prussian blue analogue was used as an anode for sodium-ion batteries. It formed a favorable solid electrolyte interface (SEI) film within ether-based electrolytes and exhibited excellent electrochemical performance. The formation of a favorable SEI layer rich in inorganics and with a dense microstructure promoted sodium ion transport and resisted volume variation of active materials. The study also revealed that the formation of the SEI layer with ether-based electrolytes is driven by the preferential decomposition of sodium salt.

Summary: Sodium tartrate is used as a dual-functional electrolyte additive to improve the reversibility of aqueous zinc-ion batteries. The additive preferentially adsorbs on the zinc surface, coordinates with zinc ions, and promotes uniform zinc deposition on the (002) plane, inhibiting side reactions and dendrite growth. This leads to long-term cycling stability and improved performance of zinc||MnO2 full cells.
