What are the outstanding characteristics of lithium iron phosphate batteries?

Source: 2020 - 04 - 10 20:06 hits: the prominent characteristics of the lithium iron phosphate battery since Thomas Edison lithium ion battery system is proposed for the first time, the lithium ion battery technology and wide application of led to a worldwide research and development boom [ 1 - 2] 。 Lithium ion battery is a kind of high performance second green battery, has high working voltage, high energy density, low self-discharge rate, no memory effect, small size, etc. The present study of cathode material LiCoO2, LiNiO2, LMin2O4, etc. However, due to the toxicity and the limited resources of cobalt, nickel acid the difficulty of preparation of lithium, manganese acid lithium cycle performance and factors, such as high performance limits its application and development. GOODENOUGH at the university of Texas in 1997, the United States and others reported that the reversible capture of the lithium iron phosphate, has attracted great attention, and has been widely research and rapid development. Compared with the traditional lithium-ion batteries, lithium iron phosphate batteries has wide raw material sources, low cost, long cycle life, good safety performance outstanding advantages, has been widely used. The characteristics of the lithium iron phosphate battery, the structure characteristics of the lithium iron phosphate batteries. On the left is the lithium iron phosphate battery structure. The anode made of olivine LiFePO4 materials, connected to the anode with aluminum foil. On the right is the battery cathode, by carbon ( Graphite) Made with copper foil connected to the cathode of the battery. Polymer membrane is among, it separates the positive and negative. Lithium ion can be through the film, and electronic can't. The battery electrolyte and sealed in a metal box.
