LMNO vs. LMO
In LMNO compared to LMO, Mn is partially replaced by Ni Incorporating Ni into the system raises the redox voltage, resulting in increased overall energy density LMNO offers a higher energy density, typically around 180-200 Wh/kg, whereas LMO possess a moderate energy density 140-160 Wh/kg LMNO has a higher cutoff voltage of 4.7 V, whereas LMO has a cutoff voltage of 4.2 V LMNO has improved low-temperature performance compared to LMO
