Latest Patents
Feng Tan holds a patent for a method for recovering lithium from waste lithium iron phosphate (LFP) material. This patent outlines a comprehensive process that includes several steps: first, adding water to the waste LFP material while controlling the pH between 0.5 to 2.0 and the ORP of the slurry between 0.05 V to 1.2 V, followed by filtering to obtain a material A. Next, sulfuric acid is added, and the mixture is heated at temperatures ranging from 100° C. to 400° C. in an air or oxygen atmosphere to produce material B. The process continues with the addition of water to material B, stirring, and filtering to yield material C. The pH of material C is then controlled between 9 to 11, and the resulting mixture is filtered to obtain material D. Material D is passed through an ion-exchange resin to produce material E, which is then reacted with a sodium carbonate solution to collect lithium carbonate.
