Direct re-lithiation strategy for spent lithium iron phosphate battery in Li-based eutectic using organic reducing agents

One of the most commonly used battery cathode types is lithium iron phosphate (LiFePO4) but this is rarely recycled due to its comparatively low value compared with the cost of processing. It is, however, essential to ensure resource reuse, particularly given the projected size of the lithium-ion battery (LIB) market.
