英文摘要: Abstract(#br)Spent carbon cathode (SCC), a hazardous solid waste produced from aluminum reduction, limits the sustainable development of the aluminum industry. This study presents a roasting treatment for removing impurities to achieve the recycling of SCC and the recycled SCC is applied as the anode of Li-ion batteries (LIBs). The effect of the roasting technologies on the carbon content of the SCC was studied, and the results show that the impurities in the SCC can be gradually removed as the temperature increases. The carbon content of the SCC can reach 97.22 % under the optimum parameters, which includ a roasting temperature of 1600 °C, roasting time of 1 h and particle size of 200 mesh. Compared to graphite and SCC, SCC treated at 1600 °C (SCC-1600) as the anodes of Li-ion batteries...
