{"product_id":"csibsenmohc","title":"Specific Electrolyte for Sodium-Ion Battery {Na2\/3Ni1\/3Mn2\/3O2 (NNMO) + Hard Carbon}, 200 g\/bottle, CSIBSENMOHC","description":"\u003cp\u003eFor a P2-type Na2\/3Ni1\/3Mn2\/3O2 (NNMO) cathode paired with a Hard Carbon (HC) negative electrode, the electrolyte must manage a more severe set of chemical and phase degradation pathways than O3-type layered oxides (such as NFM111): (1) \u003cstrong\u003eHigh-Voltage P2–O2 Phase Transition \u0026amp; Lattice Shrinkage\u003c\/strong\u003e: When charged above ~ 4.15–4.20 V vs. Na\/Na+, NNMO undergoes a major, irreversible P2-to-O2 phase transformation marked by a sharp volume collapse along the c-axis (~ 23%). This lattice shearing induces intergranular micro-cracks, exposing fresh catalytic Ni^{3+\/4+} and Mn^{3+\/4+} sites that oxidize non-aqueous solvents. (2) \u003cstrong\u003eMn^{3+} Disproportionation \u0026amp; Jahn-Teller Dissolution\u003c\/strong\u003e: Deep sodiation and high-voltage charging trigger localized Mn^{3+} formation. Solubilized Mn^{2+} ions cross the separator and deposit onto the hard carbon anode, replacing Na+ and catalytically breaking down the Solid Electrolyte Interphase (SEI). (3) \u003cstrong\u003eSevere Cell Gassing \u0026amp; Low Anode Potential\u003c\/strong\u003e: Hard carbon sodiation occurs down to ~ 0.01 V vs. Na\/Na+. Catalyzed by migrated transition metals, linear carbonates and cyclic additives (like excess FEC) rapidly decompose into gaseous products (CO2, CO, fluoro-organics), leading to rapid pouch cell swelling.\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 1000 cycles at 0.5C (2.0–4.2 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\/S037877532030759X\"\u003eC.
