{"product_id":"caseibealifnp","title":"Lithium Fluoride (LiF) Nanopowder (≥99.99%) as Battery Electrode Additive for Artificial SEI Research, 50-200 g\/bottle, CASEIBEALiFNP","description":"\u003cp\u003eIntegrating Lithium Fluoride (LiF) powder as an active electrode component or functional additive for Artificial Solid Electrolyte Interphase (a-SEI) research has become a cornerstone strategy in high-performance lithium-metal and high-capacity anode (such as silicon or lithium-alloy) development.   Although bulk LiF is classically understood as an electronic and ionic insulator (~ 10^{-13} to 10^{-14} S\/cm), nanoscale engineering and composite interphase research reveal that LiF-rich boundaries possess extraordinary electrochemical benefits.\u003c\/p\u003e\n\u003cp\u003eThe key advantages of LiF powder in SEI research are: (1) \u003cstrong\u003eMechanical Robustness \u0026amp; Shear Modulus\u003c\/strong\u003e: LiF possesses a high shear modulus, providing a rigid mechanical barrier that physically restrains local volume fluctuations and suppresses sharp dendrite penetration during high-rate stripping and plating cycles. (2) \u003cstrong\u003eInterfacial Energy \u0026amp; Synergy with Li2O\u003c\/strong\u003e: Advanced cryogenic transmission electron microscopy (cryo-HRTEM) and surface studies demonstrate that LiF forms a stable nano-interphase with Li2O. This LiF\/Li2O heterostructure and its associated grain boundaries provide low-activation-energy pathways for rapid Li+ hopping, reconciling its bulk insulating property with fast interfacial transport. (3) \u003cstrong\u003eSuppression of Parasitic Reactions\u003c\/strong\u003e: A well-designed LiF-rich a-SEI passivates reactive metal surfaces, cutting off direct contact between fresh lithium\/alloy anodes and organic carbonate solvents to drastically reduce continuous electrolyte consumption and gas evolution.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 227.712px;\" 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\u003eCASEIBEALiFNP (C-ASEI-BEA-LiFNP)\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: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eWhite powder\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 27.2875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 27.2875px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 27.2875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e7789-24-4\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 27.2875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 27.2875px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 27.2875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e≥99.99% (4N)\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 27.2875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 27.2875px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 27.2875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e25.94 g\/mol\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 27.2875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 27.2875px;\"\u003e\u003cem\u003eAverage Size Distribution\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 27.2875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~ 30-100 nm\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cspan\u003e2.64 g\/cm³ at 25°C\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 20.6px;\"\u003e\u003cem\u003eMelt Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 20.6px;\"\u003e\n\u003cp\u003e845 °C – 848 °C\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 42.7625px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 42.7625px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 42.7625px;\"\u003e50 g, 100 g, and 200 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 LiF powder in a dry place.\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\/adma.202102134\"\u003eY.
