This allows complete anode pre-doping before the main cathode lattice (especially LiFePO4 at 3.45 V) experiences high-voltage stress. (2) \u003cstrong\u003eCarboxylate Anchoring\u003c\/strong\u003e: The free -COOH functionality promotes intermolecular hydrogen bonding and chemical coordination with the surfaces of oxide cathode particles and polymeric binders (e.g., modified polyacrylic acid or carboxymethyl cellulose). This reduces the migration of de-lithiated quinone units into the electrolyte. (3) \u003cstrong\u003eElimination of Severe Gassing\u003c\/strong\u003e: Unlike classical inorganic or carboxylate donors (Li2O, Li2C2O4) that generate large volumes of CO2 gas requiring secondary pouch venting and resealing, Li2DHBA retains its aromatic carbon backbone as a condensed organic species.\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable style=\"width: 100%; height: 224.6px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 10px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCLIBCPLALiDHBA (C-LIB-CPLA-LiDHBA)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 113px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 113px;\"\u003e\u003cem\u003e\u003cbr\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 113px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC7H4Li2O4\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\/CLIBCPLALiDHBA_03_100x100.jpg?v=1788808147\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.1875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 31.1875px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 31.1875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eWhite powder\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u0026gt;99.9% (Battery Grade)\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003eMolar Mass\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e165.99 g\/mol\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.2125px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 31.2125px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 31.2125px;\"\u003e10 g, 20 g, and 50 g\/bottle\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 Li2DHBA powder 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\n\u003ca href=\"https:\/\/pubs.rsc.org\/cc\/article-abstract\/55\/72\/10737\/635091\/Self-sacrificial-organic-lithium-salt-enhanced\"\u003e\u003cspan\u003eD.
