{"product_id":"caziboctcbq","title":"TCBQ (Tetrachloro-1,4-benzoquinone, \u003e99.5%) Powder as Organic Cathode for Aqueous Zn-Ion Battery, 50-200 g\/bottle, CAZIBOCTCBQ","description":"\u003cp\u003eTCBQ (Tetrachloro-1,4-benzoquinone, commonly known as chloranil) powder is a high-performance organic small-molecule cathode material for aqueous zinc-ion batteries (AZIBs). Unlike traditional transition metal oxide cathodes (such as manganese or vanadium oxides), TCBQ relies on fast, sustainable, and reversible organic redox chemistry, making it a promising candidate for eco-friendly, high-rate energy storage.\u003c\/p\u003e\n\u003cp\u003eThe key electrochemical and redox chemistry features of TCBQ as organic cathode in aqueous zinc-ion battery are: (1) \u003cstrong\u003eReversible Carbonyl Redox Reaction\u003c\/strong\u003e: The electrochemical activity of TCBQ is governed by the reversible conversion of its carbonyl groups (C=O) to enolate groups (C-O}-). During discharge, the quinone rings accept electrons and bind incoming cations. (2) \u003cstrong\u003eCation and Proton Co-Insertion\u003c\/strong\u003e: Depending on the specific pH and electrolyte formulation, TCBQ cathodes typically operate via the reversible storage of divalent zinc ions (Zn^{2+}) and\/or protons (H+) into the molecular crystal lattice, facilitated by strong coordination bonding. (3) \u003cstrong\u003eRapid Reaction Kinetics\u003c\/strong\u003e: Because organic small molecules store charge through ion-coordination rather than sluggish solid-state lattice diffusion, TCBQ exhibits exceptionally fast charge-transfer kinetics, supporting high-rate performance.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 337.7px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 31.4491%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 68.37%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAZIBOCTCBQ (C-AZIB-OC-TCBQ)\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: 31.4491%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 68.37%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e118-75-2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 158.725px;\"\u003e\n\u003ctd style=\"width: 31.4491%; height: 158.725px;\"\u003e\u003cem\u003eChemical Formula \u0026amp; Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 68.37%; height: 158.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003csub\u003e6\u003c\/sub\u003eCl\u003csub\u003e4\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e\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\/CAZIBOCTCBQ_Structure_100x100.jpg?v=1791786199\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 29.2875px;\"\u003e\n\u003ctd style=\"width: 31.4491%; height: 29.2875px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 68.37%; height: 29.2875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e245.88\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 29.2875px;\"\u003e\n\u003ctd style=\"width: 31.4491%; height: 29.2875px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 68.37%; height: 29.2875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eLight yellow powder\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 31.4491%; height: 39.2px;\"\u003e\u003cem\u003eSpecific Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 68.37%; height: 39.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~200 mAh\/g (theoretical value is ~218 mAh\/g)\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eflat discharge plateau ~1.1 V vs. Zn\/Zn2+\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 31.4491%; height: 10px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 68.37%; height: 10px;\"\u003e\n\u003cp\u003e50 g, 100 g, and 200 g\/pack\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: Please try to store the TCBQ powder in a dry place and do vacuum drying (90-100 °C) for 12-24 h. \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:\/\/pubs.acs.org\/aamick\/article-abstract\/17\/13\/19596\/3634670\/High-Rate-Quinone-Cathodes-and-Nafion-Conditioning?redirectedFrom=fulltext\"\u003e\u003cspan\u003eP.
