What are the outstanding features of lithium iron phosphate batteries?

The outstanding characteristics of lithium iron phosphate batteries Since Edison first proposed the lithium battery system, the advancement and wide application of lithium battery technology has triggered a worldwide upsurge of research and development [1-2]. Lithium battery is a high-performance secondary green battery, which has the advantages of high working voltage, high energy density, low self-discharge rate, no memory effect, and small size. The cathode materials currently studied include LiCoO2, LiNiO2, LMin2O4, etc. However, due to the toxicity of cobalt and the limitation of resources, the difficulty of preparing lithium nickelate, the poor cycle performance of lithium manganate and high temperature performance, etc., its application and development are limited. In 1997, GOODENOUGH et al. of the University of Texas in the United States reported on the reversible capture of lithium iron phosphate, which attracted great attention and received extensive research and rapid development. Compared with the above-mentioned traditional lithium batteries, lithium iron phosphate batteries have outstanding advantages such as wide sources of raw materials, low cost, long cycle life, and good safety performance, and have been widely used. The characteristics of lithium iron phosphate batteries, the structural characteristics of lithium iron phosphate batteries. On the left is a structural diagram of a lithium iron phosphate battery. The anode is made of olivine LiFePO4 material, and is connected to the anode with aluminum foil. On the right is the negative electrode of the battery, which is made of carbon (graphite) and is connected to the negative electrode of the battery with copper foil. In the middle is the polymer film, which separates the positive and negative electrodes. Lithium ions can pass through the film, but electrons cannot. The battery is filled with electrolyte and sealed in a metal box. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
