Lithium iron phosphate batteries, like lithium manganese oxide, lithium cobalt oxide, and ternary lithium batteries, are both branches of lithium ion batteries. Its performance is mainly suitable for power applications. At this time, it is called lithium iron phosphate power battery, also called 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, its relative advantages with ternary lithium batteries and lead-acid batteries will be compared.
Ⅰ. The advantages of high temperature resistance compared with ternary lithium batteries.
The high-temperature performance of lithium iron phosphate batteries is better, which can withstand high temperatures of 350°C to 500°C, while lithium manganate /lithium cobalt oxide usually withstand only about 200°C. The materials of modified ternary lithium batteries will generally be decomposed at 200°C.
Ⅱ. The "elder" among the three kinds-the absolute advantage of long life.
Lithium iron phosphate batteries of our battery company have a longer cycle life than lead-acid batteries and ternary lithium batteries. The "long life" of lead-acid batteries is only about 300 times, up to 500 times at most; the ternary lithium battery theoretically can reach 2000 times, and the capacity will decrease to 60% when it is actually used about 1000 times; while the true cycle life of lithium iron phosphate batteries reaches 2000 times when there is 95% capacity left, and its conceptual cycle life reaches more than 3000 times.
Ⅲ. Many advantages compared with lead-acid batteries:
1. Large capacity. The monomer can be made into 5Ah~1000Ah (1Ah=1000mAh), and the 2V monomer of lead-acid battery is usually 100Ah~150Ah with a small variation range.
2. Light weight. The volume of the lithium iron phosphate battery of the same capacity is 2/3 of that of the lead-acid battery, and the weight is 1/3 of the latter.
3. Strong fast charging ability. The start-up current of lithium iron phosphate batteries can reach 2C, which can realize high-rate charging; the current requirement of lead-acid batteries is generally between 0.1C and 0.2C, which cannot achieve fast charging performance.
4. Environmental protection. Lead-acid batteries have a large amount of heavy metal-lead, which produces waste liquid, while lithium iron phosphate batteries do not contain any heavy metal, and no pollution is generated in production and use.
5. High cost performance. Although lead-acid batteries are cheaper than lithium iron phosphate batteries because of their cheap materials, they are less economical than lithium iron phosphate batteries in terms of service life and routine maintenance. Practical application results show that the cost performance of lithium iron phosphate batteries is more than 4 times that of lead-acid batteries.
Although the application of lithium iron phosphate batteries is mainly manifested in the direction of power, it can also be extended to more fields in theory, which is determined by the various advantages shown in the comparisons above. If the energy density and discharge rate have room for improvement, it is entirely possible to enter the traditional application areas.
