The performance of lithium-ion battery depends mainly on the positive and negative materials. Lithium iron phosphate is a lithium battery material that has only appeared in recent years. The large-capacity lithium iron phosphate battery developed in China in July 2005. Its safety performance and cycle life are incomparable to other materials, which are the most important technical indicators of power batteries. 1C charge and discharge cycle life of 2000 times. Single cell battery overcharge voltage 30V does not burn, puncture does not explode. Lithium iron phosphate cathode materials make large-capacity lithium-ion batteries easier to use in series. To meet the needs of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, non-polluting, good safety performance, wide source of raw materials, low price and long service life. It is an ideal cathode material for a new generation of lithium ion batteries.
This project belongs to the development of functional energy materials in high-tech projects, and is the key area supported by the national "863" plan, "973" plan and the "Eleventh Five-Year" high-tech industry development plan.
The positive electrode of lithium-ion battery is lithium iron phosphate material, which has great advantages in safety performance and cycle life. These are also one of the most important technical indicators of power battery. 1C charge and discharge cycle life can be achieved 2000 times, puncture does not explode, it is not easy to burn and explode when overcharged. Lithium iron phosphate cathode materials make large-capacity lithium-ion batteries easier to use in series.
