Lithium iron battery is a battery, a lithium battery.

The cathode material of the lithium battery is ferrous disulfide (FeS₂), the negative electrode is lithium metal (Li), and the electrolyte is an organic solvent containing lithium salt. The battery is made by winding, and the ferrous disulfide is reduced and the metal lithium is oxidized when discharged. Its energy density of about 297Wh / kg, the nominal voltage is 1.5V, the new battery open circuit voltage of nearly 1.8V, then load the terminal voltage of about 1.5V, compared to other categories of lithium batteries are low-voltage lithium batteries, the market widely used models Is AA type and AAA type. Compared with the same type of alkaline batteries and rechargeable batteries, Li / FeS₂ battery both from low temperature performance, high current discharge capacity, or storage life, have obvious advantages, the actual working discharge voltage can be compatible with alkaline batteries.

Lithium / iron disulfide battery is a new type of high-energy lithium battery, with a light weight, high energy, high current discharge capacity and so on. Stable discharge, long shelf life, excellent safety performance, especially suitable for heavy load occasions, has become the best portable electronic products power.
