应用领域

Zinc trifluoromethanesulfonate (zinc triflate, Zn(OTf)₂) is an advanced electrolyte salt widely used in aqueous zinc-ion battery research and manufacturing. Its unique triflate anion structure plays a crucial role in stabilizing the zinc electrode interface, inhibiting zinc dendrite formation, and reducing side reactions that traditionally limit the cycle life and safety of zinc-ion batteries. For example: The triflate ions interact with zinc ions, guiding their uniform electrochemical deposition on the anode surface, effectively suppressing dendrite growth for improved battery longevity.Furthermore, Electrolytes with zinc triflate maintain high capacity retention and show excellent cycling stability across many charge/discharge cycles, supporting the demands of stationary energy storage and grid-scale applications.PMID 41021778Its chemical stability minimizes undesired reactions at the electrode-electrolyte interface, resulting in higher efficiency, lower polarization, and extended battery life.PMID 34168809 Furthermore, Research demonstrates that zinc triflate promotes the formation of beneficial interface layers (e.g., ZnF₂-rich SEI), improving reversibility and reaction kinetics during battery operation.Zinc trifluoromethanesulfonate (zinc triflate, Zn(OTf)₂)dissolves readily in aqueous and hybrid electrolytes used with various cathode chemistries such as polyaniline and vanadium oxide, supporting innovations in battery design and performance. Zinc trifluoromethanesulfonate (zinc triflate, Zn(OTf)₂) is also a powerful Lewis acid catalyst utilized across a broad spectrum of organic transformations. Its high catalytic activity, thermal stability, and moisture tolerance make it an attractive alternative to traditional acid catalysts in both laboratory and industrial use. For example: Zn(OTf)₂ catalyzes one-pot synthesis of isocoumarins and pyrrolocarbazoles via tandem cyclization reactions, expanding access to valuable heterocyclic frameworks and antioxidant materials. It enables para-selective amination of anilines and phenols, supporting the synthesis of complex p-phenylenediamines and para-amino phenol derivatives under mild conditions. Zinc trifluoromethanesulfonate, Zn(OTf)₂, battery grade (≥99.9% trace metals basis) offers exceptional benefits for both zinc-ion battery technology and catalysis. In zinc-ion batteries, this high-purity electrolyte provides improved ionic conductivity, stabilizes Zn anodes, suppresses dendrite growth, and significantly enhances cycling stability and battery lifetime, key advancements for reliable energy storage solutions. In catalysis, Zn(OTf)₂ acts as a robust, recyclable Lewis acid for a wide range of organic transformations, delivering high reaction efficiency, selectivity, and operational versatility to pharmaceutical, fine chemical, and industrial syntheses. This grade supports breakthroughs in sustainable energy storage and green chemistry at research and manufacturing scales.
