{"product_id":"cazibeadhp","title":"DHP (Dimethyl (hydroxymethyl)phosphonate, DEHMP, \u003e99.0%) as Electrolyte Additive for Aqueous Zinc Ion Battery, 25-100 g\/bottle, CAZIBEADHP","description":"\u003cp\u003eDHP (Dimethyl (hydroxymethyl)phosphonate, C3H9O4P) is a functional organophosphorus compound featuring both a polar phosphonate ester group and a hydroxyl group. When evaluated as an electrolyte additive or co-solvent component in Aqueous Zinc-Ion Batteries (AZIBs), it operates via targeted solvation sheath restructuring and interfacial passivation.\u003c\/p\u003e\n\u003cp\u003eIts key functional roles in AZIB are shown below:\u003cstrong\u003e \u003c\/strong\u003e(1) \u003cstrong\u003eSolvation Shell Engineering \u0026amp; Water Activity Suppression\u003c\/strong\u003e: The oxygen atoms in the phosphoryl (P=O) and hydroxyl (-OH) groups possess a high electron-donor capability, allowing DHP molecules to strongly coordinate with Zn^{2+} ions. By entering the primary or secondary coordination sphere of zinc ions, DHP displaces free water molecules, significantly reducing bulk water activity. This suppression mitigates parasitic side reactions like the Hydrogen Evolution Reaction (HER) and zinc corrosion. (2) \u003cstrong\u003eIn-Situ Artificial SEI \/ Protective Interphase Formation\u003c\/strong\u003e: Phosphonate-based molecules exhibit high adsorption energy and chemical affinity toward zinc metal surfaces. During initial cycling, DHP participates in constructing an artificial, robust Solid Electrolyte Interphase (SEI) rich in inorganic-organic hybrid zinc-phosphonate and phosphate species. This passivating layer blocks direct contact between the active zinc substrate and aqueous solution. (3) \u003cstrong\u003eUniform Zn^{2+} Flux and Dendrite Suppression\u003c\/strong\u003e: The localized surface film promotes uniform ionic adsorption sites, homogenizing the local electric field and Zn^{2+} flux distribution. This prevents localized tip growth, ensuring smooth, highly reversible, and dendrite-free zinc plating\/stripping.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 298.125px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 34.5852%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.0938%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eCAZIBEADHP (C-AZIB-EA-DHP)\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: 34.5852%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.0938%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e24630-67-9\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 145.725px;\"\u003e\n\u003ctd style=\"width: 34.5852%; height: 145.725px;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.0938%; height: 145.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e9\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eP\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CAZIBEADHP_Structure_100x100.jpg?v=1791310718\" alt=\"\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 34.5852%; height: 35.6px;\"\u003e\u003cem\u003eAppearance \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.0938%; height: 35.6px;\"\u003e\n\u003cp\u003eColorless Liquid\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 34.5852%; height: 35.6px;\"\u003e\u003cem\u003eMolar Mass\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.0938%; height: 35.6px;\"\u003e\n\u003cp\u003e140.08 g\/mol\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 34.5852%; height: 10px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.0938%; height: 10px;\"\u003e\n\u003cp\u003e25 g, 50 g, and 100 g\/bottle\u003c\/p\u003e\n\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: (1) Please store the DHP liquid in a dry area (glovebox or dryroom is preferred)\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\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adfm.202516270\"\u003e\u003cspan\u003eH.
