/* LMnO / LMO */
''Most Li-manganese batteries blend with lithium nickel manganese cobalt oxide (NMC) to improve the specific energy and prolong the life span. This combination brings out the best in each system, and the LMO (NMC) is chosen for most electric vehicles, such as the Nissan Leaf, Chevy Volt and BMW i3. The LMO part of the battery, which can be about 30 percent, provides high current boost on acceleration; the NMC part gives the long driving range.''

|Lithium Manganese Oxide
|-
|Voltages
|3.70V (3.80V) nominal; typical operating range 3.0–4.2V/cell
|-
|Specific energy (capacity)
|100–150Wh/kg
|-
|Charge (C-rate)
|0.7–1C typical, 3C maximum, charges to 4.20V (most cells)
|-
|Discharge (C-rate)
|1C; 10C possible with some cells, 30C pulse (5s), 2.50V cut-off
|-
|Cycle life
|300–700 (related to depth of discharge, temperature)
|-
|Thermal runaway
|250°C typical. High charge promotes thermal runaway
|-
|Applications
|Power tools, medical devices, electric powertrains
|-
|Comments
|High power but less capacity; safer than Li-cobalt; commonly mixed with NMC to improve performance.
