| Abstract Scope |
Lithium (Li) is the lightest energy critical element used in manufacturing of active cathode material of LIBs. Thus, consumption of lithium is constantly increases in the LIBs. Meanwhile, LIBs becomes obsolete when reached its end-of-life and results in generation of huge amount of spent LIBs. Present study reports the roasting and leaching process for selective recovery of Li from active cathode material. At first, cathode material was roasted to study different process parameters viz. roasting temperature, time and mass ratio to optimize the condition to convert lithium cobalt oxide cathode materials into water soluble lithium complex. It was found that cathode material converted into lithium sulfate at 750 °C in two hours maintaining mass ratio of LiCoO2/ Na2SO4: 1/ 0.5. Subsequently, 96.7% Li was leached from roasted product at 80 °C in de-ionized water within two hours. Further, Li can be precipitated as lithium carbonate using sodium carbonate. |
