Generating a high-loading LiFePO4 (LFP) electrode sheet (typically defined as >25 mg/cm² or >4 mAh/cm²) is the most effective way to improve the energy density of LFP cells, which are inherently limited by their lower theoretical capacity (~170 mAh/g).
The lithium iron phosphate (LiFePO4, LFP) coated on aluminum foil electrode (disc, sheet, roll) can be used as lithium-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.
