{"product_id":"csibsepbhc","title":"Specific Electrolyte for Sodium-Ion Battery (Prussian Blue + Hard Carbon), 200 g\/bottle, CSIBSEPBHC","description":"\u003cp\u003ePairing a Prussian Blue analog (PBA) cathode—such as Na{2-x}Fe[Fe(CN)6] with a Hard Carbon (HC) anode presents an electrolyte challenge distinct from layered oxides and polyanions: (1) \u003cstrong\u003eInterstitial Water \u0026amp; HF Catalysis\u003c\/strong\u003e: Even \"zero-strain\" PBAs retain coordinate\/zeolitic crystal water (1–3 wt%), which hydrolyzes standard PF6^- salts into corrosive HF. HF strips transition metals (Fe^{2+}\/Mn^{2+}) out of the cyanide framework. (2) \u003cstrong\u003eCyanide Cage Dissolution \u0026amp; Cross-Talk\u003c\/strong\u003e: Solubilized transition metal cyanides migrate to the negative electrode, poisoning the hard carbon Solid Electrolyte Interphase (SEI). (3) \u003cstrong\u003eSevere Gas Evolution\u003c\/strong\u003e: High surface water and high-spin Mn\/Fe catalytic sites induce continuous oxidative electrolyte breakdown andCO2\/CO\/HCN gassing if not passivated.\u003c\/p\u003e\n\u003cp\u003eFor PBA system, NaClO4 is insensitive to hydrolysis, forming zero acidic fluorides. In laboratory and pre-commercial pouch cells, NaClO4 consistently yields superior capacity retention with PBAs. NaFSI resists H2O breakdown far better than NaPF6, but high-purity cells need at least a small fraction of NaPF6 (or LiDFOB\/fluorinated additives) to prevent anodic pitting of the aluminum cathode current collector above 3.6 V vs. Na\/Na+.\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\u003eCSIBSEPBHC (C-SIB-SE-PBHC)\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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1385894725123231\"\u003eC.
