Lithium Iron Phosphate (LiFePO4) Powder, Cathode Materials
Desirable as high specific energy capacity for Li-ion battery cathode mass production in electrical vehicles
Lithium iron phosphate (LiFePO4), CAS number 15365-14-7, as the cathode material for lithium-ion batteries (LIBs) have high specific energy (90 – 170 Wh Kg-1), high volumetric energy density (1200 kJ L-1) and offer good cyclic performance (~1500 cycles) with nominal cell voltage (~3.2 Vs. Li/Li+). Lithium iron phosphate has a wide but flat exothermic reaction peak at 250 – 360 °C with a much smaller heat release of 147 J g-1 and the strong P–O covalent bond prohibits oxygen release thus promoting intrinsic safety which is the top priority of an electrical vehicles (EVs). Also with relatively Low cost, long battery life, no cobalt content, it makes LFPO cells desirable for mass production for in EVs.

With an orthorhombic lattice structure in the space group Pnma, the triphylite LiFePO4 belongs to the olivine family of lithium ortho-phosphates. The unit cell structure is represented by corner-shared FeO6 octahedra and edge-shared LiO6 octahedra running parallel to the b-axis, linked together by the PO4 tetrahedra.
Carbon-coated lithium iron phosphate, surface-modified with 2 wt% of the electrochemically exfoliated graphene layers, is able to reach 208 mAh g-1 in specific capacity. Binder-free SWCNT modified LFPO cathode delivers a superior rate capacity of 161.5 mAh g-1 at 0.5 C and 130.2 mAh g-1 at 5 C, with a high-rate capacity retention of 87.4% after 200 cycles at 2 C.
