Advantages of lithium iron phosphate Batteries. What are the advantages of lithium iron phosphate batteries?

Lithium iron phosphate and lithium manganese, lithium cobalt, ternary lithium battery is the branch of lithium ion battery, its performance is mainly suitable for power applications. We usually call them lithium iron phosphate power batteries or lithium iron batteries. Therefore, the advantage of lithium iron phosphate battery mainly refers to its comparison with other batteries in power applications. In this sense, the comparative advantages of ternary lithium battery and lead-acid battery will be compared.

• First, Advantages of high temperature resistance compared with ternary lithium batteries.

The high temperature performance of the lithium iron phosphate battery is better, which can withstand the high temperature of 350°C~500°C, while the lithium manganese acid/lithium cobalt acid is usually only about 200°C, and the material of the modified three-way lithium battery will decompose roughly at 200°C.

• Second, The "elder" of the three - absolute longevity advantage.

The cycle life of lithium iron phosphate battery is longer than that of lead-acid battery and lithium ternary battery. The "long life" of lead-acid battery is only about 300 times, up to 500 times; The ternary lithium battery can reach 2000 times in theory, and the capacity will attenuate to 60% when applied to 1000 times in practice. And the real life of the lithium iron phosphate battery is up to 2000 times, at this time there is 95% capacity, its concept cycle life more than 3000 times.

• Third, More advantages compared with lead-acid battery

1. Large capacity. Monomer can be made into 5Ah~1000Ah (1Ah=1000mAh), and lead acid battery 2V monomer is usually 100Ah~150Ah, the change interval is small.
2. Light weight. A lithium iron phosphate battery with the same capacity is two-thirds the volume and one-third the weight of a lead-acid battery.

3. Fast charging ability. The starting current of lithium iron phosphate battery can reach 2C to realize high rate charging; The current of lead-acid battery is generally required to be between 0.1C and 0.2C, which cannot achieve fast charge performance.

4. Environmental protection. Lead-acid batteries contain a large amount of heavy metal -- lead, resulting in waste liquid, while lithium iron phosphate batteries do not contain any heavy metal, and are pollution-free in production and use.

5. Cost-effective. Although the purchase cost of lead-acid battery is lower than that of lithium iron phosphate battery because of its cheap material, it is less economical than lithium iron phosphate battery in service life and daily maintenance. The practical application results show that the cost performance of lithium iron phosphate battery is more than 4 times that of lead-acid battery.

Although the application range of lithium iron phosphate battery is mainly reflected in the power direction, it can also be extended to more fields in theory, which is determined by the various advantages shown in the above comparison. If the energy density and discharge rate are further improved, it is completely possible to enter the traditional application field of other types of lithium ion battery.
