Lithium iron phosphate batteries (LFPBs) have gained widespread acceptance for energy storage due to their exceptional properties, including a long-life cycle and high energy density. Currently, lithium-ion batteries are experiencing numerous end-of-life issues, which necessitate urgent recycling measures.
The lithium iron phosphate cathode battery is similar to the lithium nickel cobalt aluminum oxide (LiNiCoAlO 2) battery; however it is safer. LFO stands for Lithium Iron Phosphate is widely used in automotive and other areas .
In 2017, lithium iron phosphate (LiFePO 4) was the most extensively utilized cathode electrode material for lithium ion batteries due to its high safety, relatively low cost, high cycle performance, and flat voltage profile.
Therefore, a comprehensive and in-depth review of the recycling technologies for spent lithium iron phosphate batteries (SLFPBs) is essential. The review provided a visual summary of the existing recycling technologies for various types of SLFPBs, facilitating an objective evaluation of these technologies.
Negative electrodes (anode, on discharge) made of petroleum coke were used in early lithium-ion batteries; later types used natural or synthetic graphite. 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.
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.
