Lithium iron phosphate (LiFePO4), also called LFP, is one of the more recently-developed rechargeable battery chemistries and is a variation of lithium-ion chemistry. Rechargeable lithium iron phosphate batteries use LiFePO4 as the cathode material and graphitic carbon as the anode. Despite having a lower energy density than other lithium-ion chemistries, lithium iron phosphate batteries can provide better power density and longer life cycles. The Lithium iron phosphate powder is usually coated with carbon to improve its conductivity for its use in batteries. Carbon-coated lithium iron phosphate (C-LiFePO4) powders have been produced commercially on a large scale with a controlled solid-state reaction.

Note:

  1. As the primary particles of the product are nano-sized and the specific surface area is large, more binder is added in the electrode formula.
  2. Carbon aluminum foil is suggested as the current collector. This is to improve the contact between the active material and substrate and thus reduce the internal resistance of the battery, and also, it can improve the adhesion of the electrode to the substrate.
  3. The tap density of the electrode is suggested ~2.0g/cc.
