LiFePO4 (LFP) Coated Aluminum Foil as Cathode Electrode (Disc, Sheet, Roll) for Li-Ion Battery, CLIBCELFP

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. The roll shape with double-side coating is designed for cylindrical cell electrodes after slitting.

Rating and Cycling

Notes: (1) Please store the LFP electrodes in a dry area (glovebox is preferred); (2) The battery electrodes are highly recommended to be dried at 80-100°C in a vacuum oven for 6-12 h before use.
