Lithium-ion batteries are widely used in many technological devices such as cell phones, laptops, and hybrid/electric vehicles. Currently, lithium oxides, primarily lithium cobalt oxide [], ternary lithium oxide [], lithium nickel oxide [], lithium iron phosphate [], and lithium manganese oxide [], are being used as cathode active materials in commercial lithium-ion
While lithium iron phosphate (LFP) did not have the energy density of a cobalt cathode, its materials, iron and phosphorus, were far cheaper. LFP batteries also proved to be very stable, making them less of a fire risk, and they could last for a very large number of charge and discharge cycles.
