What are the characteristics and advantages of lithium iron phosphate battery as a power core?

In the post-industrial era, the speed of automobile popularization has greatly exceeded our imagination. While bringing high efficiency and convenience, the emission of a large amount of exhaust gas has also added a lot of pressure to the environment, and with the soaring oil price and carbon dioxide emissions, it has brought greenhouses. With the emergence of problems such as effects, it is even more urgent to find new energy sources to replace traditional energy sources. Liquid hydrogen, fuel power batteries, etc. are good choices, but there are problems such as high price and immature technology. Generally, lead-acid batteries have relatively low use costs, but they are heavy, low energy density, and short in life. There are still potential Problems such as heavy metal pollution. The new generation of electric vehicles uses a new type of lithium iron phosphate battery as the core of its power. This green power has many characteristics and advantages: 1. The safety is quite high. To be used as the power of the car, safety is the overriding primary consideration. Although the safety of general lithium batteries can be basically guaranteed, there is a possibility of fire and explosion under extreme conditions. Lithium iron phosphate battery, as the second-generation product of lithium battery, has stable physical performance, coupled with built-in protection functions such as overvoltage, undervoltage, overcurrent, and overcharge, so it will not explode or fire. It is currently the only absolutely safe product in the world. lithium battery. Due 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 improper use of lithium batteries, lithium iron phosphate batteries will not explode even if they are thrown into the fire. The high temperature stability can reach 400500°C, which guarantees the inherent high safety of the battery; it will not explode or burn due to overcharge, high temperature, short circuit, or impact. After strict safety detection, there will be no explosion even in the worst traffic accidents. 2. Long life and low cost. As a power lithium ion battery, the service life (cycle performance) is closely related to the overall cost of use. Compared with the general lithium battery's cycle life of about 500 times, the lithium iron phosphate battery can be charged and discharged at room temperature. 1500 times, the capacity retention rate is more than 95%, and the cycle life of 50% capacity is more than 2000 times. The continuous mileage of the battery is more than 500,000 kilometers, and it can be used for about five years, which is 8 times that of lead-acid batteries. It is 3 times that of hydrogen batteries and about 4 times that of lithium cobalt oxide batteries. In addition, its processing and manufacturing cost itself is lower than that of ordinary lithium batteries, which will undoubtedly greatly reduce the use and maintenance costs of electric vehicles. At the same time, the discharge performance of the lithium iron phosphate battery is also very good, the power curve is stable, and the ability to resist overdischarge is strong. Generally, the lithium battery cell is discharged after being lower than 3.2V, and it is overdischarged, which may lead to scrap. However, the lithium iron phosphate battery still has energy release at 2.8V, and there is no problem of scrapping below 2.5V. 3. Easy to use and solve. We know that Ni-MH and Ni-Cd batteries have a strong memory effect. Generally, lithium batteries also have a certain memory effect problem. They should be filled as much as possible, which will bring inconvenience to the daily use of electric vehicles. Lithium batteries have no such phenomenon and have low self-discharge; no memory effect, no matter what state the battery is in, it can be charged and used at any time, no need to first discharge and then recharge. At the same time, the battery has excellent fast charging characteristics. It can be fully around 95%. The solution to the problem after the end of the battery life is also worthy of our attention. The lithium iron phosphate battery does not contain any heavy metals and rare metals, is non-toxic, non-polluting, and meets regulations. It is an absolutely green battery. There is a large amount of lead in lead-acid batteries. , If it is not properly resolved after its disposal, it will cause secondary pollution to the environment, and the lithium iron phosphate material has no pollution during processing and use.
