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

Can Lithium Iron Phosphate Battery be used in electric bicycles?

Ordinary Lead Acid Batteries are relatively cheap to use, but they are heavy, have low energy density, short life and potential problems such as heavy metal pollution.

Can be used in electric bicycle batteries, lithium iron phosphate, but electric bicycles are important lead-acid batteries, lithium-ion batteries, after all, the price is expensive, although it is cheaper than lithium iron 3 yuan, but the ability is also low, electric bicycles are important low-end products, consumers usually attach importance to price, so lithium-ion batteries have been promoting less than ideal.

Because the production of lithium-ion iron phosphate batteries is inconsistent, to a separate battery management system, the positive electrode will form a problem of elemental iron, resulting in a micro short circuit of the battery, which is also the most taboo material in the battery. This is also the main reason why Japan does not use this material as a positive electrode material forLiFePO4 Battery.

Product consistency is poor and management is much more difficult than with lead-acid batteries. If one battery dies, it's hard to replace just one. So maintenance and repair is also a problem with these products.

The advantages of the Lithium Iron Phosphate Battery as a lithium power battery for electric vehicles are

1. High safety

Safety is the most important consideration when driving. Although the safety of ordinary lithium-ion batteries can be guaranteed in principle, there is a possibility of fire and explosion under extreme conditions. Lithium-ion iron phosphate battery as the second generation of lithium-ion battery products, its physical performance is stable, coupled with the battery pack built-in overvoltage, undervoltage, overcurrent, overcharge and other protection functions, no explosion, no fire, is the world's only absolutely safe lithium-ion battery.

2. Long life and low cost

Power Lithium Battery, service life performance (cycle) of the total cost of use is closely related, and ordinary lithium-ion battery,500 times compared to the cycle life of lithium iron phosphate battery 1500 times charge and discharge cycle at room temperature, the retention capacity of more than 95%, and 50% of the output reaches more than 2000 times the life cycle, the battery life is 500000 continuous miles 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 lithium iron phosphate battery is also very excellent, the power curve is stable, and the ability to resist overdischarge is strong. Ordinary lithium-ion battery below 3.2V, excessive discharge, may lead to scrap. However, the lithium iron phosphate battery still has 2.8V energy release, even if it is lower 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 to 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 without first discharging and then recharging.

5. Fast charging

Lithium Iron Phosphate battery has good fast charging characteristics. It can be charged quickly with a special charger, and the charge can reach 95% in half an hour.

6. Green battery

Lithium Iron Phosphate Batteries do not contain heavy metals and rare metals, non-toxic, pollution-free, in accordance with the provisions of this law, absolutely green batteries, lead-acid batteries have a large number of lead, if not properly disposed of waste, will cause secondary pollution of the environment, and lithium iron phosphate materials production and use, pollution-free.

That's why not all electric cars are powered by lithium ion iron phosphate batteries. Lithium-ion iron phosphate batteries have higher safety and longer cycle life. In terms of stability, the performance is very good. In the current political environment, lithium iron phosphate batteries have more obvious advantages.
