O3-Type NaNi0.4Fe0.2Mn0.4O2 (NFM424) Powder 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.
