Lifepo4 Bateria Lithium Iron Battery 

The full name of lithium iron battery is lithium iron phosphate lithium-ion battery, because its performance is particularly suitable for power applications, so some people call it "lithium iron power battery". (hereinafter referred to as "lithium-iron batteries")
Working principle of lithium iron battery (LiFePO4)
The internal structure of the LiFePO4 battery: on the left is the olivine structure of LiFePO4 as the positive electrode of the battery, which is connected to the positive electrode of the battery by aluminum foil, and in the middle is a polymer separator, which separates the positive electrode from the negative electrode, but the lithium ion Li can pass through and the electron e- cannot pass, and the right is the negative electrode of the battery composed of carbon (graphite), which is connected with 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 sealed by a metal shell.
When the LiFePO4 battery is charged, the lithium-ion Li in the positive electrode migrates to the negative electrode through the polymer separator. During discharge, the lithium-ion Li in the negative electrode migrates through the separator to the positive electrode. Lithium-ion batteries are named because lithium ions migrate back and forth when charging and discharging.
The main performance of LiFePO4 battery
The nominal voltage of the LiFePO4 battery is 3.2 V, the termination charge voltage is 3.6 V, and the termination discharge voltage is 2.0 V. Due to the different quality and process of positive and negative electrode materials and electrolyte materials used by various manufacturers, there will be some differences in their performance. For example, the capacity of the same model (standard battery of the same package) is quite different (10%~20%).
