| description | A comprehensive recycling method for a waste lithium iron phosphate battery relates to a waste lithium ion battery recycling technology, and particularly comprises: first selectively extracting lithium, and then using a lithium extraction residue to prepare iron phosphate, the using the lithium extraction residue to prepare the iron phosphate comprising: adding the lithium extraction residue to water to form a slurry, adding hydrochloric acid and stirring to react, so that iron is completely dissolved, performing solid-liquid separation, on the basis of iron and phosphorus contents of the obtained liquid, adding trisodium phosphate or ferric chloride, and then adding a sodium hydroxide solution to precipitate crude iron phosphate; and then performing reverse three-stage washing to remove impurities to obtain a battery iron phosphate product. The problem of environmental protection is solved and meanwhile, all of the valuable elements are recycled, and a relative cost is greatly reduced by about 25%. |
