Lithium-Manganese Dioxide cells comprises of a metallic lithium anode and a hard solid
manganese dioxide as a cathode which is immersed in a non-corrosive and non-toxic organic electrolytic solution. It delivers the voltage of 3.0V and are cylindrical in shape.

Lithium is used as an ideal negative electrode as it offers lowest potential amongst other chemical elements therefore it is offering the highest cell voltage. 3.0V Lithium Manganese dioxide batteries are widely used.

This 3.0v LiMnO2 Cells are widely used for motherboards, Fire sensors, CNC and PLC Machines. LiMnO2 Batteries offers a advantage over lithium cathode batteries
i.e LISOCl2, LISC2CL2 is the lower passivation at the anode, which helps to avoid and reduce voltage drop at the beginning of the load.

A main disadvantage of this batteries are it offers lower energy density which means it is most favorable for memory backups.
