Recovered LMO has therefore been used as a reagent to form Li4Mn2O5 and Li2MnO2.25F (these compositions were selected due to constraints imposed when using LMO as a reagent, see Equation and 2). These both have a cation disordered rocksalt structure (Fm3 ̅ m space group) and have been shown to provide a high capacity when used as cathode materials. XRD patterns of the materials show that the disordered rocksalt structure has been successfully formed (Figure and Figure ). This is the first example of the use of recycled EV material for the synthesis of these phases. the lattice parameters of the materials which are similar to literature values. The Mn oxidation state is 3+ for Li4Mn2O5 and 3.5+ for Li2MnO2.25F therefore the average Mn ionic radius is smaller in Li2MnO2.25F leading to a consequently smaller lattice parameter. The (111) peak is not present for Li2MnO2.25F, this could be due to F-doping changing the long-range order in the structure. 36,37 Electrochemical testing of Li4Mn2O5 and Li2MnO2.25F shows that they give an excellent average first cycle specific discharge capacity of 293 and 279 mAh g -1 , respectively (Figure ). Both materials experience a capacity fade resulting in a discharge capacity of 215 and 168 mAh g -1 after 10 cycles which corresponds to a 73.4 and 60.2% capacity retention. Capacity fade is very common for rocksalt type materials and similar materials synthesised using pristine reagents experience a similar capacity fade when cycled under comparable conditions (Figure ). The results, however, show that recovered LMO can successfully be upcycled into new cathode materials. This therefore provides a route to recycle these end-of-life LIB materials into a valuable product, especially if studies can be performed to improve the capacity retention of disordered rocksalt materials.
