Cell voltage Lithium manganese dioxide

The lithium-manganese dioxide high voltage cell introduced by Sanyo in 1975 is now manufactured by numerous companies, using specially prepared high density Mn02. The OCV is in the range 3.0-3.5 V and typical... 

Cells of the lithium-fluorocarbon system are very close by their characteristics to the cells of the lithium-manganese dioxide system. Though the working voltage of fluorocarbon-lithium cells is lower than the voltage of manganese dioxide-lithium cells, such cells can in many cases be interchangeable.

Lithium manganese dioxide batteries have become very prominent in recent years for military applications which are now widespread. Like sulfur dioxide batteries these are usually foimd in multicell packs often with dual voltage and cell sizes. The voltage of the system is similar to sulfur dioxide, so no major device changes are required. Typical batteries with their applications are given in Table 2 [1]. 

Lithium-manganese dioxide cylindrical and button cells arc eminently suited for applications requiring short-duration heavy-pulse discharge superimposed on a low background current. The cell can withstand 25000 such discharges (1.25 s on, 15 min off) at 20°C before the eell voltage drops. 

As a rule, manganese dioxide-lithium cells are discharged to the final voltage of 2 V the rated voltage is 3 V. The cells function in the temperature range of -20 to +50°C and can be stored for 10 years without any significant self-discharge. 

SAFT lithium-thionyl chloride cells exhibit a highly stable service voltage and a far greater capacity than conventional zinc-manganese dioxide and carbon-zinc cells of the same size and configuration.
