Lithium ferro phosphate battery pack refers to lithium ion batteries that use lithium iron phosphate as the positive electrode material. It does not contain precious elements such as cobalt, the price of raw materials is low, and phosphorus and iron are abundant in the earth's resources, so there will be no supply problems.

1. Features of lithium ferro phosphate battery pack

Compared with the more common lithium cobalt oxide and lithium manganate batteries on the market, lithium ferro phosphate battery packs have at least the following five advantages: higher safety, longer service life, no heavy metals and rare metals ( Low cost of raw materials), support for fast charging, and wide operating temperature range.

However, lithium iron phosphate batteries also have some performance defects, such as low tap density and compaction density, resulting in low energy density of lithium-ion batteries; high material preparation costs and battery manufacturing costs, and battery yield Low, poor consistency; poor product consistency, etc.

Compared with ternary batteries, lithium ferro phosphate battery packs are safe, long-lived, and resistant to high temperatures; ternary batteries are light in weight, high in charging efficiency, and resistant to low temperatures. The two have become the two heroes of lithium batteries due to their different adaptability.

2. New energy vehicle power battery

The development of domestic new energy vehicle power batteries has always been controversial: lithium manganate, ternary lithium, and lithium ferro phosphate battery packs, but most companies that make new energy vehicles will choose lithium ferro phosphate battery packs. The lithium iron phosphate power battery has a cycle life of more than 2000 times, and can be used for 2000 times with standard charging (5 hours rate). Under different environments, there will be different discharge rates, and the minimum discharge rate can reach 0.5c , the maximum discharge rate can reach 10C.

From the perspective of the application market, the current application fields of lithium ferro phosphate battery packs include new energy vehicles, energy storage, 5G base stations, two-wheelers, heavy trucks, electric ships and other fields.

The application in the field of new energy vehicles accounts for the largest proportion, including new energy passenger cars, new energy buses and new energy special vehicles; in the energy storage field, lithium ferro phosphate battery packs account for more than 94%, including new batteries and echelon batteries, the main application In the fields of UPS, backup power supply and communication energy storage; the future development of the electric ship market is expected to be good, and all applications in this field are currently lithium ferro phosphate battery packs; lithium ferro phosphate battery packs have also begun to be applied in the two-wheeler battery swap market. .

China is the country with the largest investment and largest production and sales volume in the field of lithium ferro phosphate battery packs in the world. There is no need to worry about the supply of goods, and it does not contain any precious metals. Moreover, iron oxide and lithium carbonate, the main raw materials for the production of cathode materials, are very abundant in China, which can greatly The most important thing is the stability of lithium ferro phosphate battery pack at high temperature, which can reach above 390 ℃, which ensures the inherent high safety of the battery, and will not be caused by overcharge, high temperature, short circuit, and impact. Explosion or burning can easily pass the needle stick experiment.
