Lithium iron phosphate is a new electrode material for lithium ion batteries. Its characteristics are large discharge capacity, low price, non-toxic, and does not cause environmental pollution. Countries around the world are competing to achieve industrial production.

However, its low energy density affects capacitance.

The main production method is high-temperature Solid-phase synthesis, and the product index is relatively stable.

The performance of lithium-ion battery mainly depends on the positive and negative electrode materials. Lithium iron phosphate as the positive electrode material of lithium-ion battery has only appeared in recent years. The domestic development of high-capacity Lithium iron phosphate battery was in July 2005. Its safety performance and cycle life are incomparable to other materials, and these are also the most important technical indicators of power batteries. The 1C charging and discharging cycle life reaches 2000 times. The overcharge voltage of a single battery is 30V, and it does not burn or explode when punctured. The Lithium iron phosphate cathode material makes the high-capacity lithium ion battery easier to use in series. To meet the needs of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, pollution-free, good safety performance, wide source of raw materials, low price, and long service life, making it an ideal positive electrode material for the new generation of lithium-ion batteries.

This project belongs to the development of functional energy materials in high-tech projects, and is a key support area for the national "863" plan, "973" plan, and "11th Five Year Plan" high-tech industry development plan.

Lithium ion batteries are still mainly small capacity and low-power batteries, and medium to large capacity and medium to high power lithium-ion batteries are still being tested for large-scale production, gradually making lithium-ion batteries widely used in medium to large capacity UPS, medium to large energy storage batteries, electric tools, and electric vehicles.
