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 evolution of LFP technologies provides valuable guidelines for further improvement of LFP batteries and the rational design of next-generation batteries. As an emerging industry, lithium iron phosphate (LiFePO 4, LFP) has been widely used in commercial electric vehicles (EVs) and energy storage systems for the smart grid, especially in China.
In this overview, we go over the past and present of lithium iron phosphate (LFP) as a successful case of technology transfer from the research bench to commercialization. The evolution of LFP technologies provides valuable guidelines for further improvement of LFP batteries and the rational design of next-generation batteries.
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.
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.
Lithium iron phosphate batteries officially surpassed ternary batteries in 2021 with 52% of installed capacity. Analysts estimate that its market share will exceed 60% in 2024.
