Advantages of lithium iron phosphate battery as power lithium battery pack

1. The security is quite high

To be a car power, safety is the overriding primary consideration. Although the safety of ordinary lithium batteries can be basically guaranteed, there is a possibility of fire and explosion under extreme conditions. As the second generation of lithium battery, lithium iron phosphate battery has stable physical properties, and cooperates with the built-in protection functions of overvoltage, Undervoltage, overcurrent and overcharge in the battery pack. It does not explode and does not ignite. It is the only absolute safety in the world. Lithium-Ion Battery. Thanks to the use of high thermal stability materials and meticulous process design, battery safety and reliability are greatly enhanced. Compared with the explosion that may occur in the improper use of lithium batteries, lithium iron phosphate batteries will not explode even if they are thrown into the fire. High-temperature stability up to 400 ° C -500 ° C, to ensure the inherent high safety of the battery; will not explode or burn due to overcharging, over-temperature, short circuits, impact. After rigorous safety testing, there is no explosion even in the worst traffic accidents.

2. Long life and low cost

As a power battery, the service life is closely related to the overall cost of use. Compared with the cycle life of an ordinary lithium battery of about 500 times, the lithium iron phosphate battery can be charged and discharged at a temperature of 1500 cycles, and the capacity retention rate is over 95%. The cycle life of % capacity has reached more than 2000 times. The continuous mileage life of the battery is more than 500,000 kilometers. It can be used for about five years. It is 8 times that of lead-acid batteries and 3 times that of nickel-hydrogen batteries. It is a lithium cobalt oxide battery. 4 times or so. In addition, its manufacturing cost itself is lower than ordinary lithium batteries, which will undoubtedly greatly reduce the use and maintenance costs of electric vehicles.

At the same time, the lithium iron phosphate battery has excellent discharge performance, stable power curve, and strong anti-over-discharge ability. After the ordinary lithium battery core is lower than 3.2V, the discharge is over-discharge, which may lead to scrapping. However, lithium iron phosphate batteries have energy release at 2.8V, and there is no problem of scrapping below 2.5V.

3. Easy to use and handle

Nickel-metal hydride and nickel-cadmium batteries have strong memory effects. Ordinary lithium batteries also have certain memory effect problems. They need to be “full-filled” as much as possible, which will cause inconvenience to the daily use of electric vehicles, and lithium iron phosphate batteries have no such phenomenon. Self-discharge is small; no memory effect, no matter what state the battery is in, it can be used with charging, no need to discharge and recharge first. At the same time, the battery has excellent fast charging characteristics, and it can be charged quickly with a dedicated charger, which can be sufficient for about 95% in half an hour. The problem of handling after the end of battery life is also worthy of our attention. Lithium iron phosphate battery does not contain any heavy metals and rare metals is non-toxic, non-polluting, and meets the requirements. It is an absolute green battery, and there is a large amount of lead in lead-acid batteries. If it is disposed of improperly after disposal, it will cause secondary pollution to the environment, and lithium iron phosphate material will be free from pollution during production and use.
