Electrochemical testing of LMNO shows that it gives an average first cycle specific discharge capacity of 119 mAh g -1 (Figure , capacity retention is 96.8% after 10 cycles). This is higher than the recovered LMO (figure ) and comparable to pristine LMNO (Figure ). There are voltage plateaus at ~ 4 V due to Mn 3+/4+ redox and at ~ 4.7 V due to Ni 2+/4+ redox. The presence of some Mn 3+ is common for LMNO and is often observed when LixNi1-xO impurities are present and the disordered structure is formed.
