“…The use of reducing or oxidizing agent would improve the expected yield. As recommended by [8 ], who got in sulfuric acid (1.25M, 60 minutes and at the temperature of 60°C) as a lixiviant and without adding an oxidant, a 93% lithium recovery with 13.3% for manganese.…”

A typical Li-ion-nickel manganese cobalt (NMC), battery is more than 90% composed of about Mn (2%) , Al (5%) , Ni (9%), graphite (10%), Cu (12%), Li (16%, as LCE equivalent), and Co(39%). The observed and more and more predicted increase in the number of recycling efforts leading to the use of green chemistry and the global mushrooming of the LIB recycling plants and sites, would make the lithium battery producers auto sufficient in the required storage energy related metal components. Using a projective analysis of the impact of the circularity of the end-of-life of lithium-ion batteries, this paper rings a bell on either the need for diversification or for new products development from countries naturally endowed with minerals resources termed as energy transition natural resources.

Using oxidizing compounds to handle the recycling of discarded lithium batteries has advanced significantly in recent years. One of the most prominent methods is the sintered electrode powder treatment using pre‐used additives, with an aqueous solution of the oxidizing agent fueling highly selective lithium extraction and transition metals retention in the refractory material. Herein, phosphoric acid (H3PO4) was used as the exchanger and hydrogen ions provider, the oxidant (K2S2O8) activity was driven by heating, the raw material structure was deformed and adjusted by the oxidizing drive, and lithium was exhausted, while manganese was converted into manganese(III) phosphate hydrate and manganese dioxide insoluble material. The optimized conditions resulted in a lithium leaching rate of 94.16% and a separation factor of 95.74%, while the corresponding manganese leaching rate was limited to less than 5%. The X‐ray diffraction, X‐ray spectroscopy, scanning electron microscopy, and inductively coupled plasma mass spectrometry measurements were used to investigate the influence of oxidation driving force and lithium leaching. Finally, the lithium leach solution was continuously stirred with sodium carbonate in boiling water to obtain the precipitate, which was separated and washed several times to obtain high‐purity lithium carbonate.
