{"product_id":"csibana3sbap","title":"Sodium-Antimony (Na3Sb) Alloy Powder for Na-Ion Battery Anode, 5 g\/bottle, CSIBANa3SbAP","description":"\u003cp\u003eSodium-Antimony (Na3Sb) alloy powder is an advanced high-capacity intermetallic anode and sacrificial pre-sodiation additive for sodium-ion batteries (SIBs). Delivering a high theoretical specific capacity of approximately 660 mAh\/g, antimony reacts reversibly with sodium through multi-step alloying transitions, making it a prominent candidate for high-energy sodium storage systems.\u003c\/p\u003e\n\u003cp\u003eThe key characteristics and electrochemical behavior of the Na-Sb alloy powder are: (1) \u003cstrong\u003eTheoretical Capacity\u003c\/strong\u003e: ~ 660 mAh\/g based on the full conversion to Na3Sb. (2) \u003cstrong\u003eOperating Potential\u003c\/strong\u003e: Exhibits a relatively low and flat operating plateau around 0.5-0.8 V vs. Na\/Na+, which effectively avoids sodium dendrite formation during high-rate charging while maintaining a favorable cell voltage profile. (3) \u003cstrong\u003eDual Function\u003c\/strong\u003e: Pre-synthesized Na3Sb powder functions either as a direct high-capacity composite anode or as a sacrificial sodium source blended into hard carbon electrodes to compensate for initial irreversible capacity loss and maximize initial Coulombic efficiency (ICE).\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 139.85px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 51.0125px;\"\u003e\n\u003ctd style=\"width: 34.0848%; height: 51.0125px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7343%; height: 51.0125px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSIBANa3SbAP (C-SIB-A-Na3SbAP)\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: 34.0848%; height: 35.6px;\"\u003e\u003cem\u003eAlloy Type\/Chemical Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7343%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eNa3Sb\u003c\/span\u003e\u003cspan\u003e\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: 34.0848%; height: 35.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7343%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e5 g\/pack\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 17.6375px;\"\u003e\n\u003ctd style=\"width: 34.0848%; height: 17.6375px;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.7343%; height: 17.6375px;\"\u003e\n\u003cp\u003eThe whole package with sodium-antimony powder should be opened and operated inside a glove box with Argon Gas and moisture less than 1%RH (0.1 ppm is better).\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\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\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/full\/10.1002\/advs.77935\"\u003e\u003cspan\u003eS.
