{"product_id":"csibsepwhc","title":"Specific Electrolyte for Sodium-Ion Battery (Prussian White + Hard Carbon), 200 g\/bottle, CSIBSEPWHC","description":"\u003cp\u003eUnlike conventional Prussian Blue (PB, which typically starts in a sodiated-poor or oxidized state), Prussian White (PW, nominally Na{2-x}Mn[Fe(CN)6] with x \u0026lt; 0.2) is pre-sodiated and highly reduced (Fe^{2+}\/Fe^{2+} or Mn^{2+}\/Fe^{2+}). When paired with an un-sodiated Hard Carbon (HC) anode in a full cell, Prussian White supplies the entire active Na+ inventory, including the irreversible capacity loss (ICL) required to form the initial Solid Electrolyte Interphase (SEI). However, Prussian White presents unique degradation mechanisms that dictate electrolyte formulation: (1) \u003cstrong\u003eSevere Air\/Moisture Sensitivity \u0026amp; Hydrolysis\u003c\/strong\u003e: High sodium content and low transition-metal oxidation states make PW powders vulnerable to ambient moisture, trapping residual surface coordinate water. Standard NaPF6 reacts with this residual water to generate corrosive HF. (2) \u003cstrong\u003eMn^{2+}\/Fe^{2+} Leaching \u0026amp; Anode Poisoning\u003c\/strong\u003e: Even low concentrations of HF or unpassivated surface states cause transition metal dissolution. These free cations shuttle across to the hard carbon anode, replace Na+ in the SEI, and catalytically decompose organic SEI components. (3) \u003cstrong\u003eSevere Initial Cycle Gassing\u003c\/strong\u003e: Sacrificial water oxidation and rapid early SEI formation cause pronounced gas evolution (H2, CO2, and trace cyanogen-derived species) during the first charge.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 118.6px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 36.7054%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9736%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSIBSEPWHC (C-SIB-SE-PWHC)\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: 36.7054%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9736%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eColorless Liquid\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 27.8px;\"\u003e\n\u003ctd style=\"width: 36.7054%; height: 27.8px;\"\u003e\u003cem\u003eElectrolyte Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9736%; height: 27.8px;\"\u003e\n\u003cp\u003eUndisclosed recipe from leading manufacturer that has been well demonstrated in pilot-scale SIB. \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 36.7054%;\"\u003e\u003cem\u003eHumidity Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9736%;\"\u003e\n\u003cp\u003e\u0026lt;20 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 36.7054%;\"\u003e\u003cem\u003eAcid Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9736%;\"\u003e\n\u003cp\u003e\u0026lt;100 ppm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 36.7054%;\"\u003e\u003cem\u003ePerformance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9736%;\"\u003e\n\u003cp\u003e\u0026gt;90% capacity retention after 500 cycles at 0.5C (2.1–3.8 V) (\u003cspan style=\"color: rgb(255, 42, 0);\"\u003efor reference only\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: 36.7054%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 62.9736%; height: 19.6px;\"\u003e\u003cspan\u003e200 g\/bottle\u003c\/span\u003e\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 specific SIB electrolyte in the glovebox due to its sensitivity to humidity.\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:\/\/chemistry-europe.onlinelibrary.wiley.com\/doi\/full\/10.1002\/batt.202300533\"\u003eA.
