On the left side of the lithium iron phosphate battery is the positive electrode made of olivine structure LiFePO4 material, which is connected to the positive electrode of the battery by aluminum foil. 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. In the middle is a polymer separator, which separates the positive electrode from the negative electrode. Lithium ions can pass through the separator but electrons cannot pass through the separator. The inside of the battery is filled with electrolyte, and the battery is hermetically sealed by a metal case.1.We are a leading lithium battery manufacture with 12 years experience. 2.We have lifepo4 energy storage battery, power wall battery, high voltage lifepo4 battery and some portable battery for outdoor. 3.We provide the most competitive ex-factory prices, and A+ cell batteries with CATL and BYD battery cell.Lithium iron phosphate battery has a series of unique advantages such as high working voltage, high energy density, long cycle life, green environmental protection, etc., and supports stepless expansion, and can store large-scale electric energy after forming an energy storage system. The lithium iron phosphate battery energy storage system consists of a lithium iron phosphate battery pack, a battery management system (Battery Management System, BMS), a converter device (rectifier, inverter), a central monitoring system, a transformer, etc.
