Na3V2(PO4)2F3 (NVPF) Coated Aluminum Foil as Cathode Electrode (Disc, Sheet, Roll) for Na-Ion Battery, CSIBCENVPF

Na3V2(PO4)2F3 (NVPF) coated on aluminum foil electrode (disc, sheet, roll) 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. The roll shape with double-side coating is designed for cylindrical cell electrodes after slitting.
