Coating a modified layer on the current collector is a common strategy to improve the reversibility of Zn plating/stripping. Hydrophilic modifier with high zincophilicity, usually affords uniform Zn deposition but exhibits intrinsic limitations in repelling water molecules, while hydrophobic modifiers shows excellent water-resistance. To enhance side-reaction inhibition, we increased the hydrophobicity of the CuTCNQ modifier by replacing CuTCNQ with its fluorinated analog, Cu(F4-TCNQ), on the Cu current collector. The hydrophobicity was enhanced, as indicated by a contact angle of 139.2°, which endowed the Zn anode with a remarkably electrochemical longevity by regulating the crystallographic arrangement of Zn metal, and preventing water-involved hydrogen evolution reactions as well as surface corrosion. The symmetric cell with F4-TCNQ@Cu as the anode current collector operated stably for up to 990 h at a current density of 2 mA cm-2. This performance surpassed that of bare Cu (190 h) and the hydrophobic analog TCNQ@Cu (450 h). This work provides a new strategy for the design of high-utilization zinc anodes and offers a unique perspective on evaluating the effect of hydrophobicity on the lifespan of Zn battery.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"701 ","pages":"138633"},"PeriodicalIF":9.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144811536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, two fundamental challenges impede its practical application: irreversible nanosheet restacking during synthesis seriously compromising Na+ ion diffusion, and structural collapse during cycling causing catastrophic capacity fade. Addressing these limitations, we proposed a metal-organic framework (MOF)-mediated structural transformation strategy to construct hierarchical hydrangea-like NiPS3/C microspheres through carbonization and phospho‑sulfurization of Ni-BPDC (BPDC = 4,4'-biphenyldicarboxylic) precursor. The unique architecture manifested multiple advantageous features: (i) randomly oriented NiPS3 nanosheets ensuring abundant electrochemical active sites and efficient electrolyte permeation; (ii) interconnecting conductive carbon networks enabling ultrafast electron transport; and (iii) spatially distributed carbon nanoparticles helping accommodate volume changes. Benefiting from these synergistic effects, the developed NiPS3/C electrode delivered outstanding electrochemical performance, including high specific capacity (1107.8 mAh g-1 at 0.1 A g-1) and superb cycling stability (98.2% capacity retention after 1000 cycles at 5.0 A g-1). Through in-situ/ex-situ structure diagnostics, we decoded the dynamic phase evolution during sodiation/desodiation, revealing a conversion-alloying mechanism.

Herein, a cauliflower-like MnO/carbon composite (NMOC) with hierarchical porous architecture is designed and fabricated through NaCl phase-dynamic regulation strategy by using a cost-effective manganese tartrate as the precursor. The dynamic NaCl template not only directs the self-assembly of MnO nanoparticles into three-dimensional interconnected porous frameworks but also facilitates the in-situ formation of an ultrathin (∼2 nm) carbon coating layer. As a high-performance cathode material for AZIBs, this unique structural configuration of NMOC establishes abundant Zn2+/H+ diffusion pathways, exposes high-density active sites, and significantly enhances reaction kinetics. Meanwhile, the strengthened Mn-O-C interfacial coupling and carbon confinement effect collectively suppress Mn dissolution, mitigate volume variation, and promote charge transfer dynamics. As a result, the NMOC cathode delivers an exceptional capacity of 561 mAh g-1 at 0.2 A g-1 and demonstrates ultra-stable cycling performance with 190 mAh g-1 retained after 2000 cycles at 2 A g-1 and nearly 100 % capacity retention (127 mAh g-1) after 2500 cycles at 4 A g-1.
