“…This process allows not only the recovery or the graphite but also the separation of the copper [267]. Anode recycling can include electrolysis processes to remove the Cu foil, and precipitation with Na2SO4 to recover the graphite that can be used in new batteries with excellent cycling stability and high coulombic efficiency [268]. The spent graphite can also be reconverted in 2D graphene oxide that can be used for other applications, using a modified Hummers method [272].…”

“…However, few studies are available for the recovery of Cu foil separately. Recently, Cao et al [5] developed the electrolysis approach for the separation of graphite from Cu foil. An electrolytic cell was made with the recovered LIB anode as an anode and graphite plate as a cathode in Na 2 SO 4 electrolyte.…”

“…), 3D metallic current collectors (foam, mesh, coated substrates), and carbonaceous current collectors have been developed to replace the commercialized substrates to further upsurge the energy density of the LIB. [ 5 ] Still, more efforts are required to achieve this goal since these developed current collectors have their own setbacks. However, commercial, traditional current collectors of LIBs have been subjected to slight modifications in their thickness in academia and industry over the past three decades.…”

Al and Cu foils are the irreplaceable current collectors for Li‐ion batteries (LIBs), and have a great impact on the performance. The sustainability and cost of the current collectors are important factors to improve the circular economy of the battery technologies, and it can be achieved by the effective recycling of spent LIBs. Spent LIBs are a valuable resource with potential environmental hazards owing to the presence of a lot of metals and materials, urging the researchers to recycle/reuse via effective technologies. Of critical importance in this field, is current industry/research efforts toward improving cathode materials; however, the crucial problem is the efficient separation of current collectors from the electrode materials. In this line, this perspective offers the different strategies involved in the separation of current collectors from the electrode materials of spent LIBs and suggests future directions for researchers to develop efficient recycling methodologies.

Recycling the degraded graphite is becoming increasingly important, which can helped conserve natural resources, reduce waste, and provide economic and environmental benefits. However, current regeneration methods usually suffer from the use of harmful chemicals, high energy and time consumption, and poor scalability. Herein, we report a continuously high‐temperature heating (≈2000 K) process to directly and rapidly upcycle degraded graphite containing impurities. A sloped carbon heater is designed to provide the continuous heating source, which enables robust control over the temperature profile, eliminating thermal barrier for heat transfer compared to conventional furnace heating. The upcycling process can be completed within 0.1 s when the degraded graphite rolls down the sloped heater, allowing us to produce the upcycled graphite on a large scale. High‐temperature heating removes impurities and enhances the graphitization degree and (002) interlayer spacing, making the upcycled graphite more suitable for lithium intercalation and deintercalation. The assembled upcycled graphite||Li cell displays a high reversible capacity of ≈320 mAh g−1 at 1 C with a capacity retention of 96% after 500 cycles, comparable to current state‐of‐the‐art recycled graphite. The method is a chemical‐free, rapid, and scalable way to upcycle degraded graphite, and is adaptable to recycle other electrode materials.
