A lithium iron phosphate battery has superior rapid charging performance and is suitable for electric vehicles designed to be charged frequently and driven short distances between charges. This paper describes the results of testing conducted to evaluate the capacity loss characteristics of a newly developed lithium iron phosphate battery.
In this paper the most recent advances in lithium iron phosphate batteries recycling are presented. After discharging operations and safe dismantling and pretreat-ments, the recovery of materials from the active materials is mainly performed via hydrometallurgical processes.
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.
This review summarizes the electrochemical failure mechanism and recycling technologies of LFP batteries. 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.
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).
The degradation of LFP batteries makes it a great influence on the service life and safety of batteries [, , ]. To achieve the goal of reducing capacity degradation, it is crucial to explore the failure mechanism of LFP batteries .
