Abstract Scope |
LIB (lithium-ion battery) demand has recently undergone growth with rapid increase in electric vehicles leading to enormous consumption of resources and also the generation of spent LIBs. Appropriate and effective recycling of spent LIBs is necessary to lower the dependence on natural resources and mitigate environmental risks. In this work, a thermogravimetric analyzer (TGA) was used to investigate the fundamental thermodynamics and kinetics of lithium manganese oxide (LMO, LiMn2O4) cathode and anode active material composite pellets during pyrometallurgical reactions at moderately high temperatures under reducing gas conditions. By comparing the mass loss data from the TGA and simultaneous gas analysis, the stepwise theoretical reaction mechanisms could be determined. Using the TGA results, subsequent experiments in an induction furnace under similar conditions with commercial LMO batteries verified the plausibility of an effective pyrometallurgical recycling process. |
