Abstract Scope |
In recent years, the adoption of electric vehicles (EVs) has skyrocketed due to their high efficiency and zero carbon emissions. Lithium-ion batteries are utilized in EVs because of their efficient energy storage and retainment, compact form, and light weight. Many valuable materials are used in LIBs, such as lithium, nickel, cobalt, graphite, and copper. As the demand for LIBs grows, so does the need for a sustainable recycling method to recirculate those precious materials for reuse in future LIBs. Of the precious materials utilized in LIBs, graphite has become a recent focus in battery recycling. Recycling of graphite is made difficult due to the removal of polyvinylidene-fluoride (PVDF). Using cryogenic milling (CM), PVDF can be brought below its glass transition temperature and removed from the graphite. This research proposes that using CM to remove PVDF and H2SO4 to remove copper impurities, the purity of graphite recovered will be >90%. |
