Although Mn 3+ lowers the overall voltage it has been found to improve the cycling performance of LMNO as it increases the electrical conductivity. A standard electrolyte was used in the cells therefore improvements could be made to the capacity retention by moving to a more suitable electrolyte with high voltage stability. This work nevertheless indicates that recovered LMO can be used as a reagent to synthesise LMNO which has a comparable electrochemical performance to pristine LMNO. This therefore provides a route for upcycling LMO into a commercially relevant cathode material.
