Because of its position on the periodic table, lithium-based batteries are inherently light and exhibit high cell voltages. This makes them ideal for portable equipment. Since metallic lithium reacts violently when exposed to water, all common rechargeable lithium-based cells keep their lithium in ionic form, which requires the inclusion of a safety circuit in every pack to prevent possible over-charge.
Depending on the particular cathode and anode materials used, lithium ion cells have a nominal voltage ranging from about 3.5V to 3.9V. They exhibit low self-discharge, and like lead acid cells, must be float charged as they approach a full state, though in this case, it is to prevent plating out metallic lithium. Since a continuous float state will diminish the useful life of a lithium ion cells, it is important to terminate the float charge once the pack is full.
