1. The safety is quite high as a car power, and security is the primary consideration of all over. Generally, the safety of lithium-ion batteries can be basically guaranteed, but there is a possibility of fire and explosion under extreme conditions.

The lithium iron phosphate ion battery pack serves as the second generation of the lithium-ion battery, which is stable, and then with the overvoltage, undervoltage, overcurrent, overcharge, etc. of the battery pack. It does not burst fire, is the only one in the world.

Absolutely safe lithium ion battery. Because of the use of high thermal stability materials and the dense process design, battery safety and reliability are greatly enhanced. Lithium iron ion battery packs do not explode even if they throw in the fire with improper explosions in use in improper use of lithium ion batteries.

High temperature stability can reach 400500°C, guarantees the inner safety of the battery; not due to overcharge, the temperature is too high, short circuit, and hit the explosion or burning. After strict security detection, there will be no explosion even in the worst traffic accident. 2, the long-lived cost is low as the lithium phosphate ion battery pack, the service life (cycle performance) is closely related to the overall use cost, and the lithium iron ion battery is at room temperature compared to the circulating life of the general lithium-ion battery.

Under the charged discharge cycle, the capacity retention rate is 95% or more, and 50% capacity cycle life is more than 2000 times. The battery's continuation mileage life is more than 500,000 kilometers, and it can be used for five years. It is a lead-acid battery.

8 times, 3 times the nickel-hydrogen battery, 4 times that of the lithium-cobalt ion battery. In addition, its processing and manufacturing cost itself is below the general lithium-ion battery, which will undoubtedly reduce the use and maintenance cost of electric vehicles. At the same time, the lithium iron phosphate ion battery pack discharge performance is also very excellent, the power curve is stable, the anti-over-capacity is strong, and the general lithium battery cell is below 3.

2V, and the discharge is over-placed, which may lead to scrapped. However, the lithium iron phosphate ion battery has energy release during 2.8V, and there is no problem with the scrap in less than 2.

5V. 3, use solutions to us understand that nickel-hydrogen, nickel-cadmium batteries have strong memory effects, and general lithium-ion batteries also have a certain memory effect problem. Try to be full, it will bring inconvenience to electric vehicles daily use, and phosphoric acid There is no such phenomenon, self-discharge is small; no memory effect, no matter what state, can be accompanied, no need to put it again, and the battery is fast charging characteristics, with special charger fast charge , Can be enough for half an hour to be around 95%.

After the end of battery life, it is also worthy of our concern. The lithium phosphate ion battery does not contain any heavy metals and rare metals, non-poisonous, non-polluting, in line with the definite green environmental battery, lead-acid battery in lead-acid batteries. Lead, if it solves improper after abandonment, the environment will constitute secondary pollution, and the lithium iron phosphate material has no pollution in the processing and use.

If the lithium iron phosphate ion battery is used for the increased range of electric vehicles, it is not only possible to improve the safety of the vehicle, but also more energy, which is completely enough than the power. In addition, my country's lithium resources is rich, there is no problem with cobalt and nickel resources. Therefore, my country should use the lithium iron phosphate ion battery pack as the development focus, so that it is strongly supported marketization of the reunion electric vehicle, it can effectively except for the mileage, safety, price, charging, and follow-up battery of the pure electric car.
