“…For the three EC samples, the carbon elements exist in the form of C–C/CC, C–O, and O–CO groups, with binding energies of 284.8, 286.9, and 288.8 eV (Figures E and S5A,C). , The oxygen atoms are in the form of CO, C–O–C/C–OH, and C–OOH groups related to binding energies around 531.6, 532.9, and 534.5 eV, respectively (Figures F and S5B,D). It could be concluded that the content of carbon and oxygen in the EC600 is 77.76 and 22.25 at.…”

“…Such rational-designed H-TEGO electrode can deliver up to 370 mAh g −1 at 25 C (Figure 2c-d). In another recent work, Yang et al adapted a sustainable strategy to fabricate rGO sheets from upcycling of spent carbon cathode (SCC) and through the study of different heat treatment rates of SCC materials, [32] he has discovered that the fast heating rate at 8 °C min −1 can give rise to more defects formation on the SCC-2600@rGO-8 electrode, as verified by Raman measurements (Figure 2e) indicated with a low intensities ratio of D and G bands. The defect-rich SCC-2600@rGO-8 electrode in turn results in a higher specific capacity of 753 mAh g −1 at 0.1 C when compared to slow heating rate samples (Figure 2f), while such electrode can also maintain its high specific capacity of 278 mAh g −1 at 5 C even after prolonged cycling with 2 500 cycles (Figure 2g).…”

Graphene‐based materials (GBMs) possess a unique set of properties including tunable interlayer channels, high specific surface area, and good electrical conductivity characteristics, making it a promising material of choice for making electrode in rechargeable batteries. Lithium‐ion batteries (LIBs) currently dominate the commercial rechargeable battery market, but their further development has been hampered by limited lithium resources, high lithium costs, and organic electrolyte safety concerns. From the performance, safety, and cost aspects, zinc‐based rechargeable batteries have become a promising alternative of rechargeable batteries. This review highlights recent advancements and development of a variety of graphene derivative‐based materials and its composites, with a focus on their potential applications in rechargeable batteries such as LIBs, zinc‐air batteries (ZABs), zinc‐ion batteries (ZIBs), and zinc‐iodine batteries (Zn‐I2Bs). Finally, there is an outlook on the challenges and future directions of this great potential research field.

“…Aluminium electrolysis cells are thus shut down for overhaul about every 6-7 years (Ntuk et al, 2015). The used cathode carbon blocks that are replaced and discarded during the overhaul of an electrolysis cell are called SCCs (Yang et al, 2022). The loss of cathodes also limits the life of the aluminium electrolysis cells.…”

Aluminium is produced by electrolysis using alumina (Al2O3) as raw material and cryolite (Na3AlF6) as electrolyte. In this Hall–Héroult process, the energy consumption is relatively large, and solid wastes such as spent anodes and spent pot liner, flue gas and waste heat are generated. Therefore, this article discusses from the perspective of high energy consumption and high pollution and summarizes the methods to reduce energy consumption and solve pollution problems. The functions of carbon anode, carbon cathode, refractory material and sidewall in aluminium electrolysis cells are discussed in detail. The process of aluminium electrolysis and the ways to improve the current efficiency of aluminium electrolysis cells and reduce their energy consumption are outlined. The causes and treatment methods of spent anodes, spent cathodes, spent refractories and spent spot liner are reviewed. The research progress of waste heat recovery and aluminium electrolysis flue gas purification are analysed. And the future research directions of aluminium electrolysis flue gas are provided.
