　　Introduction to lithium iron phosphate battery

　　Lithium iron phosphate battery (LIFEPO4) is also called LFP battery, which is a charging polymer battery. It is a lithium polymer battery (referred to as lithium -ion batteries or lithium batteries) for lithium iron phosphate as a positive pole material.

　　1. Lithium iron phosphate battery characteristics

　　Lithium iron phosphate batteries have the characteristics of high temperature performance, large capacity, no memory effect, light weight, and environmental protection, which makes it generally choose lithium iron phosphate as a positive electrode material for power lithium ion batteries. Essence Among them, LIFEPO4 innovation technology of lithium iron phosphate battery manufacturers (GREPOW) uses the lithium ion reaction formula, and the core technology of innovation makes many lithium ions compatible, and achieve the high power performance of the battery. life.

　　Third, the principle of working principle of lithium iron phosphate battery

　　1. Internal structure diagram

　　The figure below is the internal structural diagram of LIFEPO4. Part of the green part of the left is the positive pole of the LifePO4 battery. Connect to the positive electrode of the battery via aluminum foil. The middle polymer separates the positive and negative poles to allow the lithium ion to pass through and electronic E-but not. The battery on the right is connected to the copper foil. Electricity is full of battery.

　　2. Working principle

　　The working principle of lithium iron phosphate battery is that when the battery is charged, the lithium ion Li+in the positive pole migrates to the negative electrode through the polymer separation of the diaphragm; during the discharge process, the lithium ion Li+in the negative electrode migrates to the positive electrode through the diaphragm. In this way, the entire battery charging process is completed.
