“…Also, for automotive-type LiNMC batteries hydrometallurgical recycling facilities achieve notable recovery efficiencies already today, but this is not necessarily the case for lower-value containing batteries like SIB. [64][65][66] In fact, even for current LiFP batteries, recycling is usually limited to recovering the aluminium, copper and steel components obtained from mechanical recycling steps (crushing, shredding and mechanical separation), while the active material fraction, the socalled black mass (which contains majorly lithium., carbon, iron, and phosphorous in the case of LiFP) is usually not further processed but discarded. 39,67 To evaluate the individual recycling performance of the considered SIB cells, a cell-specic recycling model is therefore required.…”

“…Typical SLIB recycling involves physical processing (pre‐treatments, such as dismantling, crushing, screening, magnetic separation, washing, thermal pre‐treatment, etc. ), chemical treatment (pyrometallurgical or hydrometallurgical methods) or a combination of both aforementioned processes to recover valuable metals from SLIBs [1,2,5,8–10] . However, these techniques focus on cathode materials alone while largely overlooking the anode of the battery.…”

Employing Li‐ion batteries (LIBs) in portable electronics has become a necessity in the modern world but, due to the short application time for any given battery (1–3 years), the quantity of spent LIBs (SLIBs) waste is becoming substantial. Herein, a novel strategy for recycling SLIB graphite and reforming it as a valuable catalyst material for electrochemical oxygen reduction reaction was proposed. SLIB graphite has been used as a precursor material for graphite oxide, which was thereafter doped with nitrogen to prepare nitrogen‐doped graphene (NG‐Bat). The prepared NG‐Bat was characterized by various physical characterization methods and the electrochemical properties of the resulting catalyst material were investigated in alkaline media. It was found that NG‐Bat prepared from SLIB had superior physical and electrochemical properties in comparison to commercial nitrogen‐doped graphene. The findings clearly demonstrate the importance of the recycling of SLIB graphite and its great potential to be re‐applied for various applications.

Combined with the traditional preparation method of graphite anode slurry for lithium battery and the manufacturing technology of pneumatic jet, the organic solvent‐based anode slurry is selected to explore the viscosity curve under different solid–liquid ratios. It is judged that the anode slurry is a non‐Newtonian fluid. It has printability and meets the requirements of direct writing molding technology. The slurry with a solid volume fraction of 50% is selected as the printing material, the graphite anode slurry is molded on the copper foil by a pneumatic printing device and the electrochemical performance of the coin lithium‐ion battery is analyzed. The effect of printing structure and printing interval on the electrochemical performance of lithium‐ion batteries is studied and compared with batteries prepared by traditional coating processes. Finally, the linear electrode pattern is selected to discuss the effect of printing layers on the electrochemical performance of lithium‐ion batteries. The results show that the areal specific capacity of the printed electrode is significantly higher than that of the traditional coated electrode and the shape, interval, and the number of layers of the printing electrode have a significant effect on the performance of the battery.
