摘      要：Efficient extraction of electrode components from recycled lithium-ion batteries(LIBs)and their highvalue applications are critical for the sustainable and ecofriendly utilization of *** work demonstrates a novel approach to stripping graphite anodes embedded with Li^(+)from spent LIBs directly in anhydrous ethanol which can be utilized as high efficiency cathodes for aluminum-ion batteries(AIBs).Recycled graphite(RG)with foam morphology and crystal structure defects was obtained under the action of ultrasonic peeling and gas generation reaction between residual lithium-graphite interlayer compound and *** inherent open structure of RG facilitates the intercalation/deintercalation of chloralum anions(AlCl_(4)^(-))and enhances its AIB cathode *** electrochemical measurements revea that the RG cathode has a specific capacity of 123 m Ah·g^(-1)at a current of 5 A·g^(-1),which is 1.55 times higher than tha of unprocessed natural graphite and 1.25 times higher than that of commercial artificial ***,the RG cathode demonstrated remarkable stability,retaining its high particular capacity of 138.15 mAh·g^(-1)even through2000 times at 10 A·g^(-1)in a low-cost electrolyte consisting of an ionic liquid/urea/AlCl_(3)*** work offers a novel approach to reusing of graphite anode waste materials from LIBs.
