What are the advantages of lithium iron phosphate batteries as power lithium batteries for electric vehicles?

Can lithium iron phosphate batteries be used for electric bicycles? Ordinary lead-acid batteries are relatively cheap to use, but they have heavy weight, low energy density, short service life, and potential problems such as heavy metal pollution. It can be used in electric bicycle batteries and lithium iron phosphate, but electric bicycles are mainly lead-acid batteries and lithium-ion batteries. After all, they are expensive. Although they are 3 yuan cheaper than lithium iron, their capacity is also low. Electric bicycles are important low-end products. Consumers usually value price, so lithium-ion batteries have been promoting less than ideal. Because the production of lithium iron phosphate batteries is inconsistent, a separate battery management system is required. The positive electrode will form a problem of elemental iron, resulting in micro-short circuit of the battery, which is also the most taboo material in the battery. This is also the fundamental reason why Japan did not use this material as a cathode material for lithium-ion batteries. Product consistency is poor, and management is much more difficult than lead-acid batteries. If one battery is broken, it is difficult to replace only one. In this way, maintenance and repair are also a problem for these products. Advantages of lithium iron phosphate battery as a power lithium battery for electric vehicles 1. High safety and safety is the most important consideration when driving. Although the safety of ordinary lithium-ion batteries can be basically guaranteed, there is a possibility of fire and explosion under extreme conditions. As the second-generation lithium-ion battery product, the lithium iron phosphate battery has stable physical properties. In addition, the battery pack has built-in protection functions such as overvoltage, undervoltage, overcurrent, and overcharge. It does not explode or catch fire. It is the only one in the world. Absolutely safe lithium-ion battery. 2. Long life and low cost. The overall cost of power lithium battery is closely related to the service life performance (cycle). Compared with ordinary lithium ion battery, 500 times, the cycle life of lithium iron phosphate battery is 1500 charge and discharge cycles. At room temperature, the retained capacity exceeds 95%, and the output of 50% reaches more than 2,000 times the life cycle. The battery life is more than 500,000 kilometers of continuous mileage. It can be used for about 5 years, which is 8 times that of lead-acid batteries. 3. Excellent discharge performance The discharge performance of the lithium iron phosphate battery is also very good, the power curve is stable, and the ability to resist over-discharge is strong. Ordinary lithium-ion batteries will be over-discharged after the battery is below 3.2v, which may lead to scrap. But the lithium iron phosphate battery still has 2.8v energy release, even if it is less than 2.5v, there is no problem of scrapping. 4. Easy to use and handle. We understand that nickel-metal hydride batteries and nickel-cadmium batteries have a strong memory effect. Ordinary lithium-ion batteries also have some memory effect problems. They should be as full and full as possible, which will bring inconvenience to the daily use of electric vehicles. No memory effect, no matter what state the battery is in, it can be charged and used at the same time, no need to turn off the battery before charging. 5. Fast charging lithium iron phosphate battery has good fast charging characteristics. It can be quickly charged with a dedicated charger, and it can charge up to 95% in half an hour. 6. Green battery Ferrous phosphate lithium ion battery does not contain any heavy metals and rare metals, non-toxic, non-polluting, according to the provisions of this law, absolutely green and environmentally friendly batteries, lead-acid batteries have a large amount of lead, if the waste is not properly disposed of , It will cause secondary pollution to the environment, and the production and use of lithium iron phosphate materials are pollution-free. This is why not all electric vehicles are powered by lithium iron phosphate batteries. Lithium iron phosphate batteries have higher safety and longer cycle life. The performance in terms of stability is very outstanding. Under the current policy environment, lithium iron phosphate batteries have more obvious advantages.
