Lithium Manganese Oxide (Li-Mn2O4) battery is a kind of rechargeable battery with the nominal voltage of 3.7V per cell. Li-Mn2O4 battery has a higher cell voltage, more stable and higher temperature performance. Manganese is much cheaper and is more abundant; therefore, Li-Mn2O4 battery has a lower price. Li-Mn2O4 batteries are best suitable for electric vehicle and electric tools.

Principle and Reactions:

When the Li-Mn2O4 battery is charged, the lithium ions in the cathode material (lithium compound) migrate via a separator to between the layers of carbon material that form the anode, and a charging current flow. When the battery is discharged, the reverse occurs.

Positive reaction: LiMn2O4 → Li1-x Mn2O4 + xLi+ + xe−

Negative reaction: xLi+ + xe− + 6C → LixC6

Total reaction: LiMn2O4 + 6C → Li1-xMn2O4 + LixC6

Key Features:

1) High working voltage:3.7V per cell

2) High energy density

3) Good charge and discharge performance

4) High safety

5) Wide working temperature range
