A direct regeneration of cathode materials from spent LiFePO4 batteries using a solid phase sintering method has been proposed in this article. The spent battery is firstly dismantled to separate the cathode and anode plate, and then the cathode plate is soaked in DMAC organic solvent to separate the cathode materials and Al foil at optimal conditions of 30 min at 30 °C and solid liquid ratio of 1[thin space (1/6-em)]:[thin space (1/6-em)]20 g ml−1. XRD and SEM results of the spent LiFePO4 after separation show that there are some impurity phase components and irregular morphologies with many agglomerations. The …
