RECYCLING AND UPCYCLING BATTERY ANODE MATERIALS

One or more aspects of the present disclosure provides methods for recycling and upcycling battery anode materials. The methods include producing raw anode materials by processing spent battery materials containing a first anode material; purifying the raw anode materials; and generating a second anode material using the purified raw anode materials. In some embodiments, the first anode material includes graphite. The second anode material includes a graphite-silicon composite and/or a graphite-silicon oxide composite. The second anode material may be battery-grade anode materials that can be directly used in the electrodes of new batteries.
