(2) \u003cem\u003eAnode SEI Formation\u003c\/em\u003e: In low dosages (\u0026lt;1 wt%) or via trace solubilization, formate anions undergo reductive breakdown at the anode interface (1.2–1.5 V vs. Li\/Li+) to generate an organic\/inorganic mixed interphase containingLi2CO3, lithium alkyl carbonates, and hydrocarbon fragments. (3) \u003cem\u003eElectrode Cross-Talk \u0026amp; Parasitic Product\u003c\/em\u003e: In high-nickel cathode systems (e.g., NCM811), HCOOLi is frequently observed as a parasitic degradation byproduct. Under high states of charge, reactive lattice oxygen chemically attacks carbonate solvents (EC), degrading them into formic acid and formaldehyde, which subsequently react with Li+ to precipitate HCOOLi on the electrode surfaces.\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 224.6px;\"\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\u003eCLIBEALF (C-LIB-EA-LF)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 43px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 43px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 43px;\"\u003e\n\u003cp\u003eHCOOLi\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBEALF_03_100x100.jpg?v=1788327545\" 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: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e556-63-8\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\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.9% (Battery Grade)\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\u003e51.95 g\/mol\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;\"\u003e25 g, 50 g, and 100 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 store the HCOOLi powder in a dry place (the 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\u003ca href=\"https:\/\/pubs.acs.org\/aaemcq\/article-abstract\/7\/18\/7906\/133387\/Reconstruction-of-LiF-Rich-Interfaces-through-a?redirectedFrom=fulltext\"\u003e\u003cspan\u003eJ.
