{"product_id":"cbebpvpi","title":"PVP-I {Poly(vinylpyrrolidone)–Iodine} Powder as Battery Electrode Binder, 100 g\/bottle, CBEBPVPI","description":"\u003cp\u003ePoly(vinylpyrrolidone)–Iodine (PVP-I), commonly known as Povidone-Iodine, is an emerging multifunctional inorganic-organic hybrid binder and cathode component. While traditionally used as a medical antiseptic (e.g., Betadine), its unique chemical structure makes it a powerful \"smart\" material for next-generation Lithium-Iodine (Li-I₂) and Aluminum-Iodine (Al-I₂) batteries.\u003c\/p\u003e\n\u003cp\u003eIn battery systems, PVP-I acts as both a structural glue and a chemical stabilizer for the iodine active material. In iodine-based batteries, soluble polyiodide ions (I3- and I5-) tend to migrate to the anode, causing rapid capacity loss.5 The pyrrolidone rings in the PVP chain form strong hydrogen bonds and donor-acceptor complexes with iodine, effectively \"trapping\" it at the cathode. By stabilizing the triiodide (I3-) species, PVP-I ensures that the conversion reaction is highly reversible, allowing for thousands of cycles with minimal degradation.\u003c\/p\u003e\n\u003cp\u003eMoreover, PVP-I is also the \"gold standard\" for experimental Al-I₂ cathodes. It helps achieve high capacities (\u0026gt;200 mAh\/g) and excellent stability in corrosive ionic liquid electrolytes. White in Li-I2 battery system, it is used as a combined binder and active material to create ultra-stable cathodes that can survive over 9,000 cycles when paired with specialized electrolytes.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 338.125px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6875px;\"\u003e\n\u003ctd style=\"width: 32.6921%; height: 47.6875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.9482%; height: 47.6875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBEBPVPI (C-BEB-PVPI)\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: 32.6921%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.9482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e25655-41-8\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 122px;\"\u003e\n\u003ctd style=\"width: 32.6921%; height: 122px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.9482%; height: 122px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e(C6H9NO)n • xI2\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBEBPVPI_molecular_structure_160x160.png?v=1767419824\" style=\"margin-bottom: 16px; 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: 32.6921%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.9482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eDark Brown Powder\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.0375px;\"\u003e\n\u003ctd style=\"width: 32.6921%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.9482%; height: 26.0375px;\"\u003e100 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the PVPI powders in a dry place (glovebox is the best option). \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\/abs\/10.1002\/aenm.202403092\"\u003eM.
