In this paper, the application of recycled Li-ion battery spent cathodes (LIB-SC) combined with a NaHCO3/H2O2 system is presented for the first time in the literature as an alternative for the degradation of potentially toxic organic molecules. The model pollutant choice was methylene blue molecule. The spent cathode composition corresponds to LiCoO2, which was proved by the XRD and EDX. Regarding the decolorization of methylene blue solution, the addition of NaHCO3, in comparison with only H2O2, reduces the complete decolorization time by 96%. This reduction occurs because the radical CO 3 . is more stable than OH. In this way, the application of the system proposed in this article is aimed at solving two major global problems: the disposal of cell phone batteries and the pollution of liquid effluents.
