LMNO vs. LMO In LMNO compared to LMO, Mn is partially replaced by Ni and 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 Challenges LMO:

Lower energy density → less range for EVs

Capacity fade due to Mn dissolution at high temperatures LMNO:

Higher cost due to Ni

Slightly reduced thermal stability compared to pure LMO

More sensitive to electrolyte decomposition at high voltage
