Abstract Metal anodes hold considerable promise for high-energy-density batteries but are fundamentally limited by electrochemical irreversibility caused uneven metal deposition and dendrite formation, which compromise battery lifespan safety. The chaotic ion flow (or flux vortex) near the electrode surface, driving these instabilities, has remained elusive due to limitations in conventional techniques such as scanning electron atomic force microscopies, invasive incapable of probing internal structures deposits. Here, we employ in-situ X-ray computed tomography non-destructively visualize Zn on LAPONITE-coated anodes, providing insights into structural evolution orientation. Combined with computational fluid dynamics simulations, demonstrate that LAPONITE coating, its separated positive negative charge centers, suppresses ionic vortex guiding uniform, dense, vertically aligned growth along (100) plane, thereby significantly mitigating growth. This translates a 3.54-Ah Zn-MnO2 pouch cell stable performance over 100 cycles, offering viable path toward scalable, high-performance metal-anode batteries.

Interfacial instability within aqueous zinc batteries (AZBs) spurs technical obstacles including parasitic side reactions and dendrite failure to reach the practical application standards. Here, an interfacial engineering is showcased by employing a bio- derived zincophilic macromolecule as electrolyte additive (0.037 wt%), which features long-chain configuration with laterally distributed hydroxyl sulfate anion groups, has propensity remodel electric double layer of Zn anodes.

Zinc-ion batteries are promising for large-scale electrochemical energy storage systems, which still suffer from interfacial issues, e.g., hydrogen evolution side reaction (HER), self-corrosion, and uncontrollable dendritic Zn electrodeposition. Although the regulation of electric double layer (EDL) has been verified principle to select additive as regulator is misted. Here, several typical amino acids with different characteristics were examined reveal behaviors in regulated EDL on anode.

Aqueous zinc-ion batteries (AZIBs) exhibit promising prospects in becoming large-scale energy storage systems due to environmental friendliness, high security, and low cost. However, the growth of Zn dendrites side reactions remain heady obstacles for practical application AZIBs. To solve these challenges, a functionalized Janus separator is successfully constructed by coating halloysite nanotubes (HNTs) on glass fiber (GF). Impressively, different electronegativity inner outer surfaces HNTs endows HNT-GF with ion-sieving property, leading significantly transference number

Abstract Aqueous Zn‐ion batteries are an attractive electrochemical energy storage solution for their budget and safe properties. However, dendrites uncontrolled side reactions in anodes detract the cycle life density of batteries. Grain boundaries metals generally considered as source above problems but we present a diverse result.
