摘要： A method of producing a purified graphite from a recycled battery stream for use in as anode material in Li-ion batteries is described. The method comprises a leaching step to obtain a precipitate comprising graphite by filtration, which is then iteratively roasted as a slurry with an aqueous solution of a hydroxide base and subsequently washed to form a purified graphite.
