“…The significant increases of the intrinsic resistance and the charge-transfer resistance ( R ct ) of the Zn||Zn symmetrical cell with cycling are mainly ascribed to the formation of byproducts and dendrites on the surface. In contrast, the R ct of the BTO/PVT film-modified Zn symmetrical cell remains stable after different cycles, confirming the high stability of the anode–electrolyte interface …”

“…In contrast, the R ct of the BTO/PVT film-modified Zn symmetrical cell remains stable after different cycles, confirming the high stability of the anode−electrolyte interface. 40 A chronoamperometry (CA) test was carried out at an overpotential of −150 mV to characterize the Zn nucleation and growth mechanism. 41,42 As shown in Figure 2g, the continuously increasing current of bare Zn indicates a 2D diffusion process, and the stable current for the rest of the time is attributed to the 3D diffusion.…”

Aqueous rechargeable Zn metal batteries have garnered increasing attention due to their high theoretical capacity, high safety, and low cost. However, their commercialization has been impeded by the rapid cycling deterioration caused by side reactions and dendrite growth on Zn anodes. The present work explores a dielectric organic−inorganic film with a hydrophobic surface to circumvent these problems and suppress dendrite growth on the zinc anode. Dielectric BaTiO 3 /P(VDF-TrFE) (BTO/PVT) coating has been demonstrated to promote uniform zinc deposition and inhibit dendrite growth. The hydrophobic surface also regulates the Zn-ion desolvation process at the interfaces and is crucial in preventing water from harming the Zn anode surface, leading to a dendrite-free surface and little formation of byproducts. The resulting BTO/PVT@Zn anode has a long lifespan of 3000 h and an average Coulombic efficiency of 99.6% at 1 mA cm −2 . In addition, the BTO/PVT@Zn||NH 4 V 4 O 10 full cell shows a good rate capability and a long cycling lifespan.

“…With the hydrophobicity, PVDF prevents the direct contact of Zn electrodes with active water, thereby suppressing side reactions. [ 116 ] However, some researchers have point out that hydrophobic binders would inhibit Zn 2+ transport. [ 117 ] To decrease the overpotential, developing binders with high ionic conductivity and affinity provides new inspiration.…”

Aqueous zinc-ion batteries (ZIBs) with metallic Zn anodes have emerged as promising candidates for large-scale energy storage systems due to their inherent safety and competitive capacity. However, challenges of Zn anodes, including dendrite growth and side reactions, impede the commercialization of ZIBs. The regulation of the Zn/electrolyte interphase is a feasible method to achieve high-performance ZIBs with prolonged lifespan and high reversibility. Considering the as-made artificial interphase is the result of a combination of protection materials, protection mechanisms, and construction techniques, this review comprehensively summarizes the recent progress of interphase modulation and provides a systematic guideline for constructing ideal artificial layers. In addition to revealing the entanglement relationship between the failure behaviors of Zn anodes and timely concluding the emerging protection mechanisms for stable Zn/electrolyte interphase, this review also evaluates the constructing techniques in regard of commercialization, including engineering workflow, strength, shortcoming, applicable materials, and protection effect, aiming to pave the way to practical application. Finally, this review presents noteworthy points of ideal artificial layer. It is expected that this review can enlighten researchers to not only explore ideal interphases of Zn anodes for practical application, but also design other metal anodes in aqueous batteries with similar failure behaviors.

“…64 Liu et al designed an organic hydrophobic polyvinylidene fluoride (PVDF) and inorganic Santa Barbara Amorphous-15 (SBA15) hybrids were designed as a surface modification layer to stabilize Zn anode, leading to an optimized Zn/electrolyte interface with large-scale feasibility. 65 Recently, a multifunctional water-blocking polyzwitterion ionic liquid was developed by Chen's group. The tert -butyl acrylate ( tert -BuA) with water-blocking functional groups (tertiary-butyl) at the interface can thoroughly prevent H 2 O from penetrating to Zn anode surface.…”
