Bio-Carbon Assisted Carbothermal Reduction Process for the Recovery of Lithium and Cobalt from the Spent Lithium-Ion Batteries
The increase in demand for lithium-ion batteries is due to their usage in many electronic gadgets and electric vehicles. Recycling spent lithium-ion batteries plays an essential role in reducing environmental pollution and material and economic scarcity. In this paper, we employed an efficient and environmentally friendly bio-carbon based carbothermal reduction followed by a water leaching process to recover lithium and cobalt from LiCoO2(LCO)-based lithium-ion batteries. Here, the carbonized flamboyant pods (CFP) are used as a reducing agent for the carbothermal reduction process. During the carbothermal reduction process, the bio-carbon converts LiCoO2 into Co3O4 and Li2CO3. Afterwards, lithium is leached out by deionized water with a leaching efficiency of 98%, leaving Co in the residue as Co3O4. This residue is further undergoing a smelting process to recover 98.5% of Co as Co3O4. This carbothermal green recovery process is energy conserving, environmentally friendly and will bring perspective for sustainable recycling of LIBs with a minimized secondary waste.
期刊介绍:
Journal of Sustainable Metallurgy is dedicated to presenting metallurgical processes and related research aimed at improving the sustainability of metal-producing industries, with a particular emphasis on materials recovery, reuse, and recycling. Its editorial scope encompasses new techniques, as well as optimization of existing processes, including utilization, treatment, and management of metallurgically generated residues. Articles on non-technical barriers and drivers that can affect sustainability will also be considered.
