{"product_id":"csibaenasnac","title":"Sodium-Tin Alloy (Na15Sn4) Chips (D=10-16 mm, T=50 um) as Anode Electrode for Na-Ion Battery, 50 pcs\/bottle, CSIBAENaSnAC","description":"\u003cp\u003eSodium-tin alloy (Na15Sn4) chips represent the theoretical terminal sodiation phase of the tin–sodium binary system. In sodium-ion battery R\u0026amp;D, pre-formed Na15Sn4 foils or chips are employed either as freestanding high-capacity negative electrodes or as quasi-reference\/counter electrodes (substitutes for raw metallic sodium) to evaluate cathode active materials without the severe dendrite and interfacial instability associated with pure sodium metal.\u003c\/p\u003e\n\u003cp\u003eIn laboratory half-cells, testing cathodes against metallic sodium foils introduces severe experimental artifacts: mossy dendrites, high local overpotentials, and continuous electrolyte consumption. Na15Sn4 chips address several of these issues: (1) \u003cstrong\u003eStable Operating Potential\u003c\/strong\u003e: Operates along a flat two-phase equilibrium plateau (Na15Sn4 vs. Na9Sn4) between 0.08 V and 0.12 V vs. Na\/Na+. This low potential preserves high full-cell operating voltages while preventing the localized zero overpotentials that trigger sodium dendrite nucleation. (2) \u003cstrong\u003eHigher Melting Point \u0026amp; Mechanical Robustness\u003c\/strong\u003e: Pure sodium melts at 97.8 °C and creeps readily under low mechanical stack pressure. The intermetallic Na15Sn4 phase has a higher solidus temperature, allowing mechanical evaluation under higher stack pressures without separator shorting. (3) \u003cstrong\u003eSafer Handling Baseline\u003c\/strong\u003e: Intermetallic sodium-tin alloys exhibit lower chemical activity toward trace air, moisture, and organic solvents than pure elemental sodium, reducing the risk of violent exotherms.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 480.525px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.621%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSIBAENaSnAC (C-SIB-AE-NaSnAC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 45.275px;\"\u003e\n\u003ctd style=\"width: 33.621%; height: 45.275px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 45.275px;\"\u003e\n\u003cp\u003e\u003cspan\u003eNa15Sn4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 90.8px;\"\u003e\n\u003ctd style=\"width: 33.621%; height: 90.8px;\"\u003e\u003cem\u003eAlloy Chip Sizes\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 90.8px;\"\u003e\n\u003cp\u003e\u003cspan\u003eD=10, 12, 16 mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eT=50 um (active Na15Sn4)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(Al support with thickness of 30 um)\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: 33.621%; height: 35.6px;\"\u003e\u003cem\u003eBottle Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~50 pcs\/bottle\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 162.85px;\"\u003e\n\u003ctd style=\"width: 33.621%; height: 162.85px;\"\u003e\u003cem\u003eSample Package\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 162.85px;\"\u003e\n\u003cp\u003eThe sodium-tin alloy chips with or without aluminum support are firstly sealed in plastic container and further vacuum sealed in an aluminum-laminated bag.
