{"product_id":"clibeacspf6","title":"CsPF6 {Cesium Hexafluorophosphate, \u003e99.9%} Powder as Electrolyte Additive for Lithium-Ion Battery, 10-50 g\/bottle, CLIBEACsPF6","description":"\u003cp\u003eCesium hexafluorophosphate (CsPF6) is an inorganic salt widely investigated as a specialized ionic electrolyte additive for advanced lithium-ion and lithium-metal batteries. By introducing heavy, large-radius alkali metal cations (Cs+) alongside compatible hexafluorophosphate (PF6^-) anions into standard carbonate master electrolytes, CsPF6 enables precise control over interphase formation chemistry and surface electrostatics.\u003c\/p\u003e\n\u003cp\u003eThe main functional roles in electrolyte engineering are: (1) \u003cstrong\u003eSolvation Sheath \u0026amp; SEI Direction\u003c\/strong\u003e: Due to the strong preferential coordination of Cs+ with cyclic carbonates (such as Ethylene Carbonate, EC), the presence of cesium alters the primary lithium-ion solvation structure. This shifts the reduction potential of the solvated complex, promoting the preferential early-stage decomposition of the inner sheath to build an ultrathin, compact, and inorganic-rich Solid Electrolyte Interphase (SEI). (2) \u003cstrong\u003eSelf-Healing Electrostatic Shield (SHES) Mechanism\u003c\/strong\u003e: In lithium-metal systems, Cs+ ions—possessing a lower reduction potential relative to Li+—accumulate electrostatically around initial microscopic surface protuberances or hot spots. This localized positive charge builds a transient electrostatic shield that repels incoming Li+ ions, effectively mitigating dendritic growth and smoothing lithium electrodeposition. (3) \u003cstrong\u003eSuppression of Co-Intercalation\u003c\/strong\u003e: By stabilizing the interphase on standard carbonaceous hosts, CsPF6 prevents solvent co-intercalation and graphite exfoliation, notably unlocking the use of wider-temperature solvents like propylene carbonate (PC).\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 261px;\"\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\u003eCLIBEACsPF6 (C-LIB-EA-CsPF6)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 115px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 115px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 115px;\"\u003e\n\u003cp\u003eCsPF6\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBEACsPF6_Structure_100x100.jpg?v=1789854603\" 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\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\u003e277.87 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;\"\u003e10 g, 25 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 store the CsPF6 powder in the glovebox due to its sensitivity to humidity and oxygen\u003c\/span\u003e\u003cspan\u003e \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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775315010782\"\u003e\u003cspan\u003eL.
