{"product_id":"clibcplals","title":"Lithium Squarate (Li2C4O4) Powder as Cathode Pre-Lithiation Additive for Lithium-Ion Battery, 10 g\/bottle, CLIBCPLALS","description":"\u003cp\u003eLithium squarate (Li2C4O4), also known as dilithium squarate, is an emerging organic sacrificial lithium salt used for the pre-lithiation of lithium-ion batteries (LIBs) and lithium-ion capacitors (LICs). It is considered a \"green\" and high-efficiency alternative to inorganic supplements like Li5FeO4 (LFO) because it decomposes during the first charge into environmentally benign gaseous byproducts (CO or CO2) and lithium ions, leaving behind virtually no dead weight or metal residues. The key features of Li2C4O4 as lithium pre-lithiation additive are: (1) \u003cstrong\u003eNo Dead Weight\u003c\/strong\u003e: Upon oxidation, the squarate anion (C4O4)2-) decomposes into gases. This means you gain lithium ions to build a stable SEI layer without adding inactive mass that would otherwise lower the battery's overall energy density. (2) \u003cstrong\u003eSEI Stabilization\u003c\/strong\u003e: Beyond just providing lithium, its decomposition products help form a less soluble and more stable Solid Electrolyte Interphase (SEI). This leads to better capacity retention over hundreds of cycles. (3) \u003cstrong\u003eHigh Efficiency\u003c\/strong\u003e: Adding just 2.5% to 5% weight can improve first-cycle efficiency by 5% to 15% in high-capacity systems like silicon-graphite anodes.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 423.812px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCLIBCPLALS (C-LIB-CPLA-LS)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 39.2px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 39.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003ePristine Li2C4O4: White\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eLi2C4O4\/Carbon Composite: Grey or Black\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 175px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 175px;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 175px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eLi2C4O4\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBCPLALS_chemical_structure_160x160.png?v=1767588274\" style=\"margin-bottom: 16px; float: none;\"\u003e\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\u003eAdditive Types\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e(1) Pristine Li2C4O4\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e(2) Li2C4O4\/Carbon composite (carbon content is 5 wt%)\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%\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\u003epH\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e7.5-8.5\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eAddition Amount\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e2.5-5.0 wt%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 48.4px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 48.4px;\"\u003e\u003cem\u003ePre-Lithiation Mechanism\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 48.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBCPLALS_mechanism_160x160.png?v=1767581687\"\u003e\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\/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 Li2C4O4 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\u003cspan\u003e\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/full\/10.1002\/advs.202201742\"\u003eA.
