The Lithium Titanate (Li4Ti5O12) coated on aluminum foil electrode (disc, sheet, roll) can be used as lithium-ion battery anode. 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.
