| Abstract |
Various medicines may be overdue and invalid due to the untimely consumption. Herein, in order to reduce the resource waste and the environmental emission, expired lithium carbonate tablets were recycled in the form of LiFePO4/C powders via high temperature solid state reaction with the recovery of 85.8%. The obtained LiFePO4/C powders were investigated in terms of X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), tap density measurement, electronic conductivity measurement, galvanostatic charge/discharge and cyclic voltammetry (CV). As expected, LiFePO4/C powders appeared as many nanoparticles with the particle size of about 300-700 nm. Furthermore, LiFePO4/C cathode maintained the reversible specific discharge capacity above 106.7 mAh/g at 2C for 400 cycles. The satisfactory results indicated high feasibility and provided a promising strategy to recycle the expired lithium carbonate tablets. Additionally, the techno-economic analysis of recovering the expired lithium carbonate tablets was performed, and the result indicated that the recycling cost of expired lithium carbonate tablets was much cheaper than that of commercial LiCO3 feedstock. |
