“…To address the issues mentioned above, numerous methods have been proposed to improve the reversibility of Zn anodes, including Zn anode structure engineering, [ 7–9 ] artificial functional layer construction, [ 10–14 ] and electrolyte engineering. [ 6,15 ] The fabrication of a 3D structured anode with porous architecture could rebalance the local electric field by increasing the specific surface area, thus the Zn 2+ deposition morphology is improved and the dendrite growth is suppressed. [ 8 ] However, the reversibility of the Zn anode is still insufficient for practical use due to the uncontrolled water‐induced side reactions.…”

“…Moreover, almost all of the polymer protective coatings inevitably suffer from low ionic conductivity and reduced ion migration rate across the Zn/electrolyte interface, leading to an unneglectable polarization and unsatisfactory performance of the AZMBs under large current densities. [ 15 ] Therefore, although the Zn anode cycling stability could be optimized to some extent by the artificial interlayer construction, there is still a need for better strategies for high‐reversible Zn anodes.…”

As one of the most promising anodes of aqueous batteries, Zn metal faces uncontrollable side reactions and deleterious dendrite growth, which drastically compromise its cycle life and Coulombic efficiency (CE). To tackle these issues, a versatile electrolyte additive is reported that can regulate the solvation structure, adsorb on the Zn surface, and in situ generate a novel zincophilic‐microhydrophobic interphase to isolate the anode from the reactive water molecules. Benefiting from its triple effects on the water reactivity modulation, the Zn metal anode exhibits excellent reversibility with an ultra‐high average CE value of 99.92% at 5 mA cm−2 in the ZnSO4 electrolyte system, and the Zn||Zn symmetric cell with ethanesulfonamide additive achieves a long lifespan over 6000 h. The merits of ESA additives are further displayed in the Zn//MnO2 full cells and Zn ion hybrid capacitors, exhibiting excellent capacity retention of 81.60% at 5 C over 1000 cycles, and a 92.25% capacity retention over 50 000 cycles at 5 A g−1, respectively. What's more, the full cells exhibit outstanding stability of 100% capacity retention after 120 cycles at 0.1 C. This strategy shows a promising alternative for the further development of aqueous Zn metal batteries with low‐cost ZnSO4‐based electrolytes.

“…By topography modification and pore tuning realized by DIW, the sub‐milli‐net hierarchical‐porous adsorption plate (SHARP) can realize great mass transfer kinetics, working with the intrinsic nano/sub‐nano pores of the material (right image of Figure 15c). The gradient‐porous structure in SHARP is popular in energy‐related [ 197,198 ] and environmental [ 199,200 ] studies for its great heat and mass transfer kinetics. [ 201 ] Furthermore, the in situ regeneration by inner heating film conveniently extended the lifetime of SHARP, which would be a promising adsorption/catalytic component in the future.…”

Conventional adsorbents and catalysts shaped by granulation or extrusion have high pressure drop and poor flexibility for chemical, energy, and environmental processes. Direct ink writing (DIW), a kind of 3D printing, has evolved into a crucial technique for manufacturing scalable configurations of adsorbents and catalysts with satisfactory programmable automation, highly optional materials, and reliable construction. Particularly, DIW can generate specific morphologies required for excellent mass transfer kinetics, which is essential in gas-phase adsorption and catalysis. Here, DIW methodologies for mass transfer enhancement in gas-phase adsorption and catalysis, covering the raw materials, fabrication process, auxiliary optimization methods, and practical applications are comprehensively summarized. The prospects and challenges of DIW methodology in realizing good mass transfer kinetics are discussed. Ideal components with a gradient porosity, multi-material structure, and hierarchical morphology are proposed for future investigations.

“…The previous commonly used methods included binding stable and ionic conductive substances to Zn anode with binders such as PVDF to induce uniform deposition of Zn 2+ and inhibit parasitic reactions. [ 22–25 ] However, the introduction of inert substances such as PVDF increased the overall mass of the anode and hindered the interfacial dynamics to a certain extent, and it was easy to cause local uneven in the manual coating process. At present, researchers are focusing on in situ solid‐electrolyte interphase (SEI) derived from electrolyte additives, [ 26–29 ] which is simple in process and has a certain self‐healing ability to ensure the sustainability of SEI during repeated cycles.…”

The stability of aqueous Zn‐ion batteries (AZIBs) is highly dependent on the reversibility of stripping/plating Zn anode. In this work, an organic ligand etching method is proposed to develop a series of in situ multifunctional protective layers on Zn anode. Particularly, the 0.02 m [Fe(CN) 6]3− etching solutions can spontaneously etch the Zn anode, creating an in situ protective layer with unique terraced structure, which blocks the direct contact between the electrode and electrolyte and increases the area for Zn2+ ions deposition. Interestingly, all elements in the organic ligands (i.e., C, N, Zn, and Fe) exhibit strong zincophilic, significantly promoting zinc deposition kinetics and enhancing 3D nucleation behavior to inhibit zinc dendrite growth. As a result, the etched Zn anode can provide as high a Coulombic efficiency of 99.6% over 1000 cycles and sustain over 400 h long‐term stability at a high current density of 10 mA cm−2. As general validation, the small amount of metal cations additives (e.g., Ni2+, Mn2+, and Cu2+) can accelerate the synthesis of artificial interface layers with 3D structures and also regulate zinc deposition behavior. This work provides a new idea from the perspective of etching solution selection for surface modification of Zn metal anode.
