However, interfacial instability severely hinders the practical application of Li anodes. Constructing a robust solid electrolyte interphase (SEI) with optimized chemical composition and structure has been recognized as an effective strategy to overcome this challenge. Here, we propose silver trifluoroacetate (AgTFA) as a multifunctional electrolyte additive that synergistically regulates Li nucleation and promotes the formation of an anion-rich solvation structure. Through a spontaneous in situ displacement reaction, uniformly distributed silver nanoparticles (Ag NPs) are generated on the Li surface, providing abundant lithiophilic nucleation sites to enable homogeneous Li deposition. Meanwhile, trifluoroacetate anions (TFA-) with an ultrahigh donor number, together with NO3- anions participating in Li+ solvation, markedly reduce the desolvation barrier and facilitate the formation of a LiF-Li3N-rich SEI. As a result, Li||Li symmetric cells exhibit remarkable cycling stability of up to 2,500 hours at 0.5 mA·cm-2/0.5 mAh·cm-2, while Li||LiFePO4 full cells deliver a high discharge capacity of 139.8 mAh·g-1 with an excellent capacity retention of 97.28% after 200 cycles at 1.0 C. This work demonstrates a feasible strategy for constructing durable SEI layers by coupling Li nucleation regulation with anion-rich solvation chemistry.","PeriodicalId":217524,"journal":{"name":"Handbook of Smart Materials, Technologies, and Devices","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://oss.sciexplor.com/manuscript/479/publish/SMD_202534.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147908709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report the in-situ mechanical exfoliation of graphite in a mixture of hydroxyethylacrylate terminated polybutadiene urethane (HTPU) prepolymer and reactive diluent. The mixture containing exfoliated graphite nanoplatelets (GN) is directly used to prepare UV cured composite resins (G/HTPU) with various GN concentrations. Various techniques, such as scanning electron microscopy (SEM), Raman, atomic force microscopy (AFM), have been used to characterize the GN, confirming that few-layered GN are obtained after the in-situ mechanical exfoliation. The incorporation of GN exerts little effect on the curing of the coatings with a gelation around 95%, but greatly enhances the elastic modulus. Tafel polarization curves, electrochemical impedance spectroscopy (EIS) and salt-spray testing were conducted to comparatively evaluate the G/HTPU coatings with different GN loadings. The results indicate that the incorporation of GN greatly improves the corrosion resistance of the HTPU UV coatings. The self-corrosion current density (Icorr) and the charge transfer resistance (Rc) of G/HTPU-2 (0.2% GN loading) are greatly reduced to 1.03 × 10-8 A·cm-2 and increased by two magnitudes, respectively, compared to those of the parent HTPU coating. Additionally, the G/HTPU-2 coating with thickness of 100 μm can protect galvanized sheet against 0.5 mol/l sulfuric acid for at least 24 h. The practical application in protection of electronics was illustrated by coating the G/HTPU-2 on a standard printed circuit board (PCB, IPC-B-24A). No corrosion was observed after it was immersed in an artificial sweat solution even under open-circuit voltage of 12 V for 72 h and then 24 V for 48 h.","PeriodicalId":217524,"journal":{"name":"Handbook of Smart Materials, Technologies, and Devices","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://oss.sciexplor.com/manuscript/323/publish/SMD-202401.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147898295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
