Pyrolysis-Ultrasonic-Assisted Flotation Technology for Recovering Graphite and LiCoO2 from Spent Lithium-Ion Batteries
Abstract
An environmentally-friendly technology of pyrolysis-ultrasonic-assisted flotation for recovering graphite and LiCoO 2 from spent lithium-ion batteries has been evaluated in this paper. Surface properties and morphology of graphite and LiCoO 2 derived from spent lithium-ion batteries were carefully studied, and on this basis, their pyrolysis characteristics were investigated by thermogravimetry–gas chromatography–mass spectroscopy. Advanced analysis techniques, scanning electron microscopy, X-ray fluorescence spectrometry, and X-ray photoelectron spectroscopy, were utilized to analyze the effect of pyrolysis and ultrasound on the surface properties and morphology of graphite and LiCoO 2 . Flotation tests were conducted to evaluate the reinforcing effect of pyrolysis–ultrasound on flotation behavior. Results show that organic binder and electrolyte are the main reasons that graphite and LiCoO 2 are hard to separate by flotation; meanwhile, pyrolysis can effectively decompose organic binders at a pyrolysis temperature of 500 °C, and ultrasonic cleaning can effectively remove residual pyrolysis products. Pyrolysis-ultrasonic-assisted flotation can make the LiCoO 2 grade improve from 67.25% to 93.89% with the recovery improving from 74.62% to 96.88%. This research work may provide an alternative process for the preparation of high purity LiCoO 2 particles for the subsequent chemical metallurgy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
