Regenerated lithium iron phosphate cathode material and preparation method thereof |
| abstract |
The invention relates to the field of waste disposal of lithium iron phosphate, and discloses a cathode material of regenerated lithium iron phosphate and a preparation method thereof. The positive electrode material comprises: an inner core and a shell layer surrounding the inner core; in the inner core, the molar ratio of lithium:iron:phosphorus=1:1:1, and in the shell layer, the molar ratio of lithium:iron:phosphorus= (1.03‑1.15):1:(1.01‑1.05). The lithium iron phosphate waste can be prepared to obtain a qualified and usable regenerated lithium iron phosphate positive electrode material, and the reuse of the lithium iron phosphate waste can be realized. The provided lithium iron phosphate cathode material can have a core-shell structure to improve the electrochemical performance of the material. |
