NFPP is an ideal candidate for dry processing due to its structural stability. \u003c\/p\u003e\n\u003cp\u003eNFPP is a \"polyanion\" material with a 3D framework that allows fast sodium-ion diffusion. However: (1) \u003cstrong\u003eElectronic Conductivity\u003c\/strong\u003e: Like most phosphates, NFPP is an insulator. High loading increases the electron path length, necessitating a robust conductive network. (2) \u003cstrong\u003eParticle Morphology\u003c\/strong\u003e: NFPP particles are often micron-sized clusters. For dry electrodes, the particle size distribution must be optimized to ensure even distribution within the PTFE (polytetrafluoroethylene) fibril matrix.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eNa₄Fe₃(PO₄)₂P₂O₇ (NFPP) coated on aluminum foil electrode (disc, sheet) can be used as sodium-ion battery cathode. The round disc shape with single-side coating is suitable for coin cell testing, while the rectangle sheet shape with single- or double-side coating is designed for single-layer or multiple-layer pouch cell testing.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 101.462%; height: 405.6px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 19.6px;\"\u003e\u003cem\u003ePart Number \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 19.6px;\"\u003eCSIBDEHLNFPP (C-SIB-DEHL-NFPP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.6px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 31.6px;\"\u003e\u003cem\u003eCurrent collector\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 31.6px;\"\u003e15 um aluminum foil with carbon coating (1 um on each side)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 19.6px;\"\u003e\u003cem\u003eDry Coating Material\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 19.6px;\"\u003eNa4Fe3(PO4)2P2O7 (\u003ca href=\"https:\/\/echemsupplies.com\/products\/csibcnfpp432?variant=47905708245222\"\u003eNFPP432\u003c\/a\u003e) powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 19.6px;\"\u003e\u003cem\u003eActive Portion\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 19.6px;\"\u003e94.5%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 142.4px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 142.4px;\"\u003e\u003cem\u003eElectrode Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 142.4px;\"\u003e\n\u003cp\u003e(1) Round disc shape: D = 10 -15 mm\u003c\/p\u003e\n\u003cp\u003e(2) Rectangle sheet shape:\u003c\/p\u003e\n\u003cp\u003e     (a) 31 mg\/cm2, single-side, 1.93 g\/cm3, L120 mm*W90 mm\u003c\/p\u003e\n\u003cp\u003e     (b) 62 mg\/cm2, double-side, 2.3 g\/cm3, L120 mm*W90 mm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 71.2px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 71.2px;\"\u003e\n\u003cp\u003eRound disk D=10-15 mm (50 pcs\/pack)\u003c\/p\u003e\n\u003cp\u003eRectangle sheet with SS \u0026amp; DS coating (5 pcs\/pack)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 74.8px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 74.8px;\"\u003e\u003cem\u003eFirst Discharging Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 74.8px;\"\u003e\n\u003cp\u003e~105 mAh\/g (0.1 C, testing voltage range of1.5-3.5 V, Electrolyte:1.0M NaPF6 in EC:DMC:EMC=1:1:1 Vol% with 1.0%FEC)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.8px;\"\u003e\n\u003ctd style=\"width: 30.3091%; height: 26.8px;\"\u003e\u003cem\u003eFirst Columbic Efficiency\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4804%; height: 26.8px;\"\u003e94.8 %\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 NFPP432 electrodes in a dry area (glovebox is preferred); \u003c\/span\u003e\u003cspan\u003e(2) The battery electrodes are 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\u003cspan\u003e\u003ca href=\"https:\/\/chemistry-europe.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/batt.202400438\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eH.
