Lithium batteries are available in many different versions, which differ in terms of cathode, electrolyte, and separator. They are available in different designs and sizes to accommodate a wide range of applications. Because of their high voltage of 3 volts, high capacity, wide temperature range, and long shelf life (due to low self-discharge) they have a wide range of applications.

Main application areas are car keys, watches, medical equipment, toys, LED flashlights, and of course any form of memory back-up.

They come in a variety of different sizes. The cells are used either in a battery holder or pins which are welded to the cell.

Lithium is an ideal (negative) electrode material since it has the lowest potential of all chemical elements and therefore the highest possible cell voltage. Lithium manganese dioxide batteries (LiMnO2) with a voltage of 3 volts are widely used. This type is mainly used in small electronic devices, and as a backup battery for motherboards. The advantage over lithium batteries with a liquid cathode (LiSO2, LiSOCl2, LiSO2Cl2) is the lower passivation of the anode, which helps avoid voltage drops at the beginning of the load (voltage delay).

Lithium carbon fluoride mono cells (Li(CF)n), likewise with a voltage of 3 volts, are also widely used. Benefits include further increased durability and an extended temperature range with a lower self-discharge. A disadvantage is the lower current carrying capacity which means these cells are mainly used in the field of memory backup.
