Customer ServiceWith widespread applications for lithium-ion batteries in energy storage systems, the performance degradation of the battery attracts more and more attention. Understanding the battery’s long-term aging characteristics is essential for the extension of the service lifetime of the battery and the safe operation of the system.
As the lithium-ion batteries are continuously booming in the market of electric vehicles (EVs), the amount of end-of-life lithium iron phosphate (LFP) batteries is dramatically increasing. Recycling the progressively expanding spent LFP batteries has become an urgent issue.
During the long charging/discharging process, the irreversible loss of active lithium inside the LFP battery leads to the degradation of the battery's performance. Researchers have developed several methods to achieve cathode material recovery from spent LFP batteries, such as hydrometallurgy, pyrometallurgy, and direct regeneration.

Obviously, the more severe the degradation of the battery, the deeper the overgrowth of SEI film on the negative electrode . The overgrowth of SEI films depletes the active Li + from the cathode material, which in turn deepens the degradation of the battery capacity. Fig. 5. a) Flow chart of the experiment.
In addition, as shown in Fig. 5n and o, many upright and stronger lithium dendrites grew on the graphite surface . It reveals that Li-plating is one of the main causes of battery failure. The pursuit of high-energy-density LIBs has led to the development of Si anodes.
