{"product_id":"cazibeszbf","title":"Zn(BF4)2·xH2O (Zinc Tetrafluoroborate Hydrate, \u003e99.0%) Powder as Electrolyte Salt for Aqueous Zinc-Ion Battery, 50-200 g\/bottle, CAZIBESZBF","description":"\u003cp\u003eZinc tetrafluoroborate hydrate (Zn(BF4)2· xH2O) powder is a specialized, fluorinated alternative electrolyte salt utilized in advanced research for aqueous zinc-ion batteries (AZIBs). Positioned between conventional sulfates and bulky organic sulfonates\/imides, tetrafluoroborate (BF4^-) offers unique interfacial and solvation characteristics that actively modify the electrode-electrolyte boundary.\u003c\/p\u003e\n\u003cp\u003eThe key electrochemical advantages of Zn(BF4)2 as electrode salt are: (1) \u003cstrong\u003eAnion-Derived Interphase Engineering (SEI\/CEI)\u003c\/strong\u003e: Unlike sulfate ions (SO4^{2-}), which rarely participate directly in the inner Helmholtz layer reduction, the BF4^- anion can undergo controlled electrochemical or chemical decomposition during initial cycling. This contributes to the in-situ formation of a robust, inorganic-rich passivating layer containing boron and fluorine species (such as ZnF2, B2O3, and complex fluoroborates) on the zinc anode. (2) \u003cstrong\u003eSuppression of Dendrites and Side Reactions\u003c\/strong\u003e: The resulting hybrid inorganic-organic interphase promotes uniform 2D horizontal zinc electrodeposition, effectively smoothing out local electric field hotspots and mitigating dendrite growth and parasitic hydrogen evolution (HER). (3) \u003cstrong\u003eHigh Dissociation and Conductivity\u003c\/strong\u003e: The BF4^- anion is symmetrical and weakly coordinating compared to divalent sulfates, leading to weaker ion-pairing with Zn^{2+} and ensuring high ionic conductivity across a broad temperature range. (4) \u003cstrong\u003ePrevention of Basic Salt Precipitation\u003c\/strong\u003e: Similar to triflate systems, Zn(BF4)2 solutions are far less susceptible to forming insulating basic zinc sulfate by-products (Zn4SO4(OH)6 · xH2O) during localized pH shifts.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 198.925px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAZIBESZBF (C-AZIB-ES-ZBF)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 38.325px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 38.325px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 38.325px;\"\u003e\n\u003cp\u003e\u003cspan\u003eZn(BF\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003e)\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003e·xH\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e (CAS: 27860-83-9)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite Powder\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.0%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e239.00 g\/mol (anhydrous basis)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e50 g, 100 g, and 200 g\/bottle\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please store the Zn(BF4)2·xH2O powder in a dry place. \u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/full\/10.1002\/advs.202507332\"\u003eW.
