To summarise, this work reports a novel method to selectively leach low value Mn based cathode from EOL EV batteries and then upcycle into new cathode materials, the first example of this approach to synthesise high voltage spinel and disordered rocksalt phases. In contrast to previous studies, this work investigated LIB material obtained from a EOL EV which shows that this method is viable for such degraded cathode material sources. Citric acid has been shown to work as a selective leaching agent to separate cathodes containing LMO and NCA. As a development from previous work on ascorbic acid leaching, this work avoided the use of a pre-treatment NaOH delamination step and instead used citric acid as a combined leaching and delaminating acid. Recovered LMO was upcycled to form LMNO which gave a gravimetric discharge capacity of 119 mAh g -1 . Recovered LMO was also used as a reagent to form Li4Mn2O5 and Li2MnO2.25F. These showed high gravimetric discharge capacities of 293 and 279 mAh g -1 respectively in line with previous reports for pristine materials. This work illustrates the potential for recovered end of life battery materials to be manufactured into next generation cathode materials.
