Summary: This paper introduces the energy storage mechanism and current challenges of aqueous zinc-ion batteries (AZIBs), and elucidates some modifying strategies for zinc anodes from the perspectives of experiments and theoretical calculations. Experimental strategies mainly focus on constructing a dense artificial interface layer or porous framework on the anode surface, while some research teams directly use zinc alloys as anodes. Theoretical research is mainly based on adsorption energy, differential charge density, and molecular dynamics.

Summary: A polyzwitterion protective layer (PZIL) was developed to prevent dendrite formation and side reactions on zinc anode, improving the safety and stability of zinc ion batteries. The PZIL adsorbs onto the zinc metal, inhibiting side reactions, and chelates with zinc ions to regulate solvation structure. Additionally, the Hofmeister effect enhances interfacial contact during electrochemical characterization. The symmetrical zinc battery with PZIL exhibited stable performance for over 1000 hours at an ultra-high current density of 40 mA cm(-2).

Summary: By introducing an effective and non-toxic cationic electrolyte additive Rb2SO4, the issues of dendrite growth and severe side reactions during plating/stripping on the zinc anode of aqueous zinc-ion batteries (AZIBs) can be effectively addressed. The large cation Rb+ of Rb2SO4 preferentially adsorbs on the surface of zinc metal, leading to a strong shielding effect that enables the lateral deposition of Zn2+ ions and isolates water from the zinc metal, thus inhibiting side reactions.

Summary: Aqueous Zn-based batteries (AZBs) have attracted attention for their safety, cost-effectiveness, and environmental friendliness. This study focuses on solving the issue of Zn dendrite formation and improving the electrochemical stability of the batteries. By adjusting the composition of the electrolyte solvent, specifically using ethanol (EA), the uniform deposition of zinc is promoted, inhibiting the growth of Zn dendrites. Furthermore, a mixed electrolyte solvent (H2O/EA) improves the overall electrochemical performance of the Zn/KZnHCF battery.

Summary: In this study, the electrochemical performance of Zn metal anode in aqueous batteries was improved by modifying the conventional filter paper separators with chitosan. The chitosan coating allowed preferential adsorptions of proton, zinc ion and sulfate, which suppressed corrosions and hydrogen evolution reactions at Zn electrode. The interactions of zinc ion and sulfate with chitosan regulated the ion transport manner and ensured homogeneous Zn nucleation and growth. With the use of chitosan modified separators, the Zn electrode showed a long cycle life of 2900 h and a high coulombic efficiency of 99.6%. The capacity retention of Zn||MnO2 batteries was also significantly enhanced from 52.8% to 98.4% over 1000 cycles.

Summary: This paper describes the use of self-assembled monolayers modified metallic zinc as an anode for zinc-ion batteries. The modification layer suppresses side reactions and dendrite formation, resulting in improved stability and performance of the zinc anode. The modification layer prevents direct contact between water and hydrogen ions with zinc, repels anions in the solution, but attracts cations to facilitate zinc plating and stripping. The modification layer also increases the number of nucleation sites, promoting lateral growth of zinc without dendrite formation.

Summary: This study introduces a thiourea additive to improve the performance of aqueous zinc ion batteries (AZIBs) by constructing a unique metal-molecule interface, which regulates the interface chemistry of the zinc electrode and the electrolyte environment. The metal-molecule interface acts as a corrosion inhibitor to alleviate water-induced side reactions and as a regulator for promoting homogeneous zinc deposition, resulting in a corrosion-free and dendrite-free zinc anode. The zinc|zinc symmetric cell exhibits an extended lifespan and high cumulative capacity, while the zinc|V2O5 full cell shows a high capacity retention after cycles.
