Lithium iron battery

Lithium -iron battery is a type of battery, which belongs to a lithium battery.

A class of batteries in the lithium battery family, the positive electrode material is sulfide (FES2), the negative electrode is metal lithium (li), and the electrolyte is an organic solvent containing lithium salt.

Different from secondary iron batteries (lithium iron phosphate batteries), lithium -iron batteries are disposable batteries.

Lithium/sulfide battery is a new type of high -energy lithium battery, which has the characteristics of light quality, high energy, and strong large current discharge capacity. The discharge is stable, the storage life is long, and the safety performance is excellent. It is especially suitable for use in heavy loads. It has gradually become the best power supply for portable electronic products.

The positive electrode of the lithium -iron battery is a sulfide (FES2). The negative electrode is a metal lithium. The battery is made of a wound method. During discharge, the sub -sulfide is restored and the metal lithium is oxidized. Its energy density is about 297Wh/kg, the nominal voltage is 1.5V, the opening voltage of the new battery is nearly 1.8V, and the end voltage of the load is about 1.5V [3]. Compared with the lithium batteries of other categories The models used are AA and AAA types. Compared with the same model of alkaline batteries and rechargeable batteries, the LI/FES2 battery has obvious advantages in whether it is low -temperature performance, large current discharge ability, or storage life [4]. compatible.

Lithium -iron batteries are different from people's commonly referred to iron lithium batteries (LIFEPO4). The full name of the lithium lithium battery is a lithium iron phosphate battery, which belongs to the secondary lithium ion battery (charging).
