Composition ratio of lithium iron phosphate

The composition ratio of lithium iron phosphate is generally 20 mAh/g.

Lithium iron phosphate is a lithium-ion battery electrode material with the chemical formula LiFePO4. It is mainly used in various lithium-ion batteries.

LiFePO4 serves as the positive electrode of the battery. It is connected to the positive electrode of the battery by an aluminum foil. There is a polymer separator in the middle, which separates the positive electrode from the negative electrode. However, lithium Li+ ions can pass through but e- electrons cannot. Right The negative electrode of the battery is made of carbon (graphite) and is connected to the negative electrode of the battery by a copper foil. Between the upper and lower ends of the battery is the battery electrolyte, and the battery is sealed by a metal casing.

The lifespan of lithium iron phosphate batteries

is closely linked to its operating temperature. If the operating temperature is too low or too high, it will cause great hidden dangers when charging. , discharge and use process. Especially when used in electric vehicles in northern China, lithium iron phosphate batteries cannot provide normal power or the power supply is too low in autumn and winter, and the temperature of the working environment must be adjusted to maintain its performance. Home solutions to the constant temperature working environment of lithium iron phosphate batteries must consider space constraints. The most common solution is to use airgel felt as an insulation layer.

This is a lithium iron phosphate battery. If you askwhat type of lithium battery the voltage is 4V, it means you don't quite know what the principle of lithium iron phosphate battery is.

The interior of a lithium-ion battery is mainly composed of a positive electrode, a negative electrode, an electrolyte and a separator. Different materials of positive and negative electrodes and electrolytes as well as process differences give batteries different performances and different names. Currently, the cathode materials for lithium-ion batteries on the market are mainly lithium cobalt oxide (LiCoO2) and lithium manganate (LiMn2O4). There are also a few lithium-ion batteries that use lithium nickel oxide (LiNiO2) as the cathode material. The newly developed lithium iron phosphate battery is a lithium ion battery that uses lithium iron phosphate (LiFePO4, called LFP) material.same positive electrode of the battery. This is a new member of the lithium-ion battery family.

Figure 1: Working principle of lithium iron phosphate battery

In the internal structure of lithium iron phosphate battery, on the left is LiFePO4 with olivine structure as the electrode positive electrode of the battery, which is connected to the positive electrode of the battery by an aluminum foil, in the middle there is a polymer separator, which separates the positive electrode from the negative electrode, but the lithium Li+ ions can pass through through but e- electrons cannot. the negative electrode of the battery made of carbon (graphite), which is connected to the negative electrode of the battery by copper foil. Between the upper and lower ends of the battery is the battery electrolyte, and the battery is sealed by a metal casing.

When the LiFePO4 battery is charging, the ionsithium Li+ from the positive electrode migrate to the negative electrode through the polymer separator; during the discharge process, lithium Li+ ions from the negative electrode migrate to the positive electrode; through the separator. Lithium-ion batteries get their name because lithium ions migrate back and forth during charging and discharging.

After knowing the principle, you can know:

1. Depending on the material of the negative electrode, phosphoric acid with different voltages can be produced.Lithium iron.

2. Different manufacturers, if they customize batteries, can customize lithium iron phosphate batteries of different specifications according to needs.

3. The lithium iron phosphate I have seen has various specifications such as 4V, 3.3V and 2.85V.
