About LiFePO4

The internal junction of the LiFePO4 battery is LiFePO4 with an olivine structure as the positive electrode of the battery, which is connected to the positive electrode of the battery by aluminum foil, with a polymer separator in the middle, which separates the positive electrode from the negative electrode, but the lithium ion Li+ can pass through but the electron e- cannot pass , On the right is the negative electrode of the battery composed 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 electrolyte of the battery, and the battery is hermetically sealed by a metal casing.

When the LiFePO4 battery is charged, the lithium ion Li+ in the positive electrode migrates to the negative electrode through the polymer separator; during the discharge process, the lithium ion Li+ in the negative electrode migrates to the positive electrode through the separator. Lithium-ion batteries are named after lithium ions move back and forth during charging and discharging. Generally speaking, the nominal voltage of LiFePO4 battery is 3.2V, the final charging voltage is 3.6V, and the final discharge voltage is 2.0V.

There are big differences in the capacity of lithium iron phosphate power batteries, which can be divided into three categories: small ones from a few tenths to a few milliamp hours, medium ones with tens of milliamp hours, and large ones with hundreds of milliamp hours. Similar parameters of different types of batteries also have some differences. Some are used in 18650 cylindrical batteries, and some are used in prismatic batteries.
