Why Lithium Iron Phosphate Batteries May Be the Key to the LiFepo4 Cathode Material: From the Bulk to the Surface. Nanoscale. 2020, 12 (28), 15036–15044. DOI: 10.1039/ Research to Industrial Applications.
It achieved the recovery of valuable substances from SLFPBs and the regeneration of electrode material LFP, emphasizing high efficiency, energy savings, and environmental protection, while also facilitating the recycling of lithium leaching tailings and reducing costs. Fig. 11.
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 process was divided into five stages: safe pretreatment of batteries, removal of low-value collectors, leaching and extraction of high-value lithium, conversion of leaching residue into valuable materials, and regeneration of LFPB cathode electrode materials, which aimed to integrate various lithium-ion battery (LIB) recycling technologies.
With lithium-ion reduction, the battery late charge. When the terminal voltage of the battery reaches voltage. for batteries. materials. of LFP.
