Lithium iron phosphate batteries generally consist of a positive electrode, a negative electrode, a separator, an electrolyte, a casing and other accessories. The positive electrode active material is olivine-type lithium iron phosphate (LiFePO4), which can only be used after modification such as carbon coating and doping. The negative electrode active materials
Lithium-ion batteries (LIBs) have gained prominence as energy carriers in the transportation and energy storage fields, for their outstanding performance in energy density and cycle lifespan [1].However, excessive external heat abuse conditions will trigger a series of chain physical and chemical reactions, accompanied by large amounts of heat generation [2].

The efficient recycling of spent lithium iron phosphate (LiFePO4, also referred to as LFP) should convert Fe (II) to Fe (III), which is key to the extraction of Li and separation of Fe and is not well understood.

On the other hand, the cathode, typically composed of a metal oxide (such as lithium cobalt oxide or lithium iron phosphate), stores lithium ions when the battery is in a discharged state. The ions shuttle back and forth between these two components during charging and discharging, which enables the battery to store and release energy efficiently.
A lithium iron phosphate battery is a type of lithium battery that uses lithium iron phosphate as the positive electrode material. The passage further mentions other cathode materials used in lithium batteries, but the focus is on lithium iron phosphate.
As lithium ions are removed during the charging process, it forms a lithium-depleted iron phosphate (FP) zone, but in between there is a solid solution zone (SSZ, shown in dark blue-green) containing some randomly distributed lithium atoms, unlike the orderly array of lithium atoms in the original crystalline material (light blue).
Multiple lithium iron phosphate modules are wired in series and parallel to create a 2800 Ah 52 V battery module. Total battery capacity is 145.6 kWh. Note the large, solid tinned copper busbar connecting the modules together. This busbar is rated for 700 amps DC to accommodate the high currents generated in this 48 volt DC system.
The capacity of a lithium iron phosphate power lithium-ion battery can be divided into three categories: small-scale, which is a few to a few milliamperes; medium-scale, tens of milliamp-hours; and large-scale, hundreds of milliamp-hours. The capacity of individual batteries can vary greatly.
Lithium iron phosphate batteries, which use LiFePO4 as the positive electrode, meet the following performance requirements, especially during high discharge rates (5-10C discharge): stable discharge voltage, safety (non-burning, non-explosive), and long life (cycle times).
The LFP battery uses a lithium-ion-derived chemistry and shares many advantages and disadvantages with other lithium-ion battery chemistries. However, there are significant differences. Iron and phosphates are very common in the Earth's crust. LFP contains neither nickel nor cobalt, both of which are supply-constrained and expensive.
