Lithium iron phosphate powder lithium sulfate process - filter press application
2023/02/16 1891
Introduction Lithium iron phosphate powder comes partly from the trimmings produced in the process of cutting the pole pieces in the battery factory; the other part comes from the scrapped lithium iron phosphate power batteries and the recovered positive pole pieces. Both trimmings and positive electrode wafers need to be crushed, vibration sieved and separated from aluminium foil and lithium iron powder. Aluminium foil can be sold directly to aluminium refineries...
