{"product_id":"casibantp","title":"NaTiPO4 (NTP) Powder for Aqueous Na-Ion Battery Anode, 20 g\/bottle, CASIBANTP","description":"\u003cp\u003eNaTi2(PO4)3 (NTP)—often written broadly as NaTiPO4 when discussing its generic polyanionic titanium phosphate framework—is one of the premier anode (negative electrode) materials for sodium-ion batteries, particularly celebrated for its exceptional performance in aqueous sodium-ion batteries (ASIBs).\u003c\/p\u003e\n\u003cp\u003eNaTi2(PO4)3 crystallizes into a rhombohedral structure (space group R3c). (1) \u003cstrong\u003eStructural Cage\u003c\/strong\u003e: The skeleton of the material is built from corner-sharing [TiO6] octahedra and [PO4] tetrahedra. Each [TiO6] unit is linked to six [PO4] units, creating an open, robust 3D interconnected network. (2) \u003cstrong\u003eLarge Diffusion Tunnels\u003c\/strong\u003e: This open framing hosts large interstitial cavities (specifically the Na(1) and {Na(2) sites) that act as wide highways for Na+ ions. The activation energy for sodium migration through these tunnels is exceptionally low, enabling rapid ion intercalation and deintercalation. (3) \u003cstrong\u003eZero-Strain Intercalation\u003c\/strong\u003e: Because the covalent polyanionic framework is remarkably rigid, the total volume change during complete sodiation\/desodiation is \u0026lt; 1%. This \"zero-strain\" nature prevents structural collapse, particle pulverization, and mechanical peeling over thousands of cycles.\u003c\/p\u003e\n\u003cp\u003eIn an aqueous (water-based) electrolyte, the thermodynamic stability window of water is narrow (1.23 V, though practically extended to ~1.5 V - 2.0 V due to overpotentials). If an anode's operating voltage is too low (like graphite or metallic sodium at ~0 V), it will trigger severe hydrogen evolution reactions (HER), decomposing the water, building up gas pressure, and destroying the cell. At ~ 0.4 V vs. Standard Hydrogen Electrode (SHE) (which equates to its position in aqueous testing), NTP sits perfectly within the stable electrochemical window of water, effectively suppressing hydrogen gas generation while maximizing the overall cell voltage.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 511.175px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 53.275px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 53.275px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 53.275px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eCASIBANTP (C-ASIB-A-NTP)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 38.2125px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 38.2125px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 38.2125px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eNaTiPO4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6331%;\"\u003e\u003cem\u003eChemical Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eNa: 5.5 wt%  Ti: 22.6 wt%   PO4: 69.0 wt%\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: 33.6331%; height: 35.6px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003eParticle Size Distribution\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eD10: 1.6 um,  D50 =4.8 um,  D90: 9.1 um \u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 21.1375px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 21.1375px;\"\u003e\u003cem\u003eTap Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 21.1375px;\"\u003e1.50 g\/cm3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23.6625px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 23.6625px;\"\u003e\u003cem\u003eSpecific Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 23.6625px;\"\u003e0.48 m2\/g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6331%;\"\u003e\u003cem\u003epH\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%;\"\u003e10.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 56.663px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 56.663px;\"\u003e\u003cem\u003eXRD\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 56.663px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CASIBANTP_XRD_160x160.png?v=1782028272\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 201.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 201.6px;\"\u003e\u003cem\u003eFirst Discharging Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 201.6px;\"\u003e\n\u003cp\u003e~110 mAh\/g (0.1 C)\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CASIBANTP_Charge-Discharge_160x160.png?v=1782028272\" style=\"margin-bottom: 16px; float: none;\"\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e20 g\/bottle\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\u003eNotes\u003c\/strong\u003e: (1) Please store the NTP powder in a dry area (glovebox is preferred); (2) The battery powder is highly recommended to be dried at 80-100°C in a vacuum oven for 6-12 h before use.\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\u003ca href=\"https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acsami.2c00029\"\u003e\u003cspan\u003eS.
