What are the advantages of lithium iron phosphate battery?
Lithium iron phosphate battery and lithium manganate, lithium cobalt acid, ternary lithium battery is the same branch of lithium ion battery, its performance is mainly suitable for power applications, then called lithium iron phosphate power battery, also known as lithium iron battery. Therefore, the advantage of lithium iron phosphate battery mainly refers to its comparison with other batteries in power applications. In this sense, it will be mainly compared with ternary lithium battery and lead-acid battery comparative advantages.
1. High temperature resistance advantage compared with ternary lithium battery.The high temperature performance of Lifepo4 battery is better, which can withstand the high temperature of 350°C~500°C, while lithium manganate /lithium cobalt oxide usually only has about 200°C, and the material of modified ternary lithium battery will decompose at 200°C.
2.three of the "elderly" -- absolute advantage of long life. The cycle life of lithium iron phosphate battery is longer than that of lead acid battery and ternary lithium battery. The "long life" of lead-acid batteries is only about 300 times, up to 500 times. Ternary lithium battery can reach 2000 times in theory, but the capacity will decline to 60% when applied to 1000 times in practice. However, the real life of the lithium iron phosphate battery is up to 2000 times, at this time there is still 95% capacity, and its conceptual cycle life is more than 3000 times.
It has many advantages over lead-acid batteries
a.The single cell can be made into 5Ah~1000Ah (1Ah = 1000mAh), while the 2V cell of lead-acid battery is usually 100Ah~150Ah, with small variation interval.
B. Light weight. A lithium iron phosphate battery of the same capacity is two-thirds the size and one-third the weight of a lead-acid battery
c. Quick charging ability is strong. The starting current of lithium iron phosphate battery can be up to 2C, realizing high rate charging. The current of lead-acid battery is generally required to be between 0.1c and 0.2c, so the quick charging performance cannot be achieved
d. Environmental protection. Lead acid battery has a large amount of heavy metal - lead, produce waste liquid, and lithium iron phosphate battery does not contain any heavy metal, in the production and use are pollution-free
e. High cost performance. Although lead-acid batteries are cheaper than lithium iron phosphate batteries due to their low cost of materials, they are less economical than lithium iron phosphate batteries in terms of service life and daily maintenance. Practical application results show that the cost performance of lithium iron phosphate battery is more than 4 times that of lead acid battery.
Lithium iron phosphate battery application scope is mainly manifested in the direction of power, but also in theory can be extended to more areas, it is by the comparison of the various advantages, if in such aspects as energy density and the discharge ratio do ascend, traditional into other types of lithium ion battery application field is also possible
