In the development of electric vehicles, battery technology has become the most critical link. Although the battery technology of automobiles is developing better and better, battery technology does not mean that it can not be used now, but it still needs to be developed. Lithium iron phosphate battery is one of the important batteries. This kind of battery has not been paid attention to in the past. Now, because of the existence of lithium iron phosphate battery, people also have a certain understanding of it. Lithium iron phosphate battery is also known as ternary lithium battery. It is a secondary battery and belongs to tertiary battery in lithium ion battery applications. The main principle is that the lithium iron phosphate battery uses iron phosphate as the cathode material to form the cathode material of lithium ion battery. Lithium iron phosphate battery, as the main energy release of ternary lithium battery, is due to the charge discharge activity of lithium iron phosphate cathode material. It has advantages in the number of cycles, so it can repeat about 500 times in daily use without considering the attenuation problem; In addition, as a negative electrode material, its service life will be longer than that of ternary, and it can better perform the electrical storage work.

Range

The biggest advantage of lithium iron phosphate battery is its high energy density. Under the same conditions, the energy density of power type lithium iron phosphate battery can reach 170 Wh/kg (such as EV, passenger cars), nearly twice as high as the ternary lithium battery currently used, so it is the most important power system in electric vehicles. In many countries, the technology upgrading and development of electric vehicle industry are encouraged, so the technical level of electric vehicles in China is constantly improving. At present, the number of electric vehicles in China has exceeded 5 million. According to statistics, the sales volume of new energy vehicles in the first five months of this year in China has exceeded 500000, with a year-on-year growth of 175%. Among them, pure electric vehicles have accounted for 85.7%. Therefore, the demand for electric vehicles will maintain a strong growth trend.

Security

Safety is also an important part of electric vehicles. Because the safety problem of electric vehicles has always been a big pain point of electric vehicles. The main reason is that electric vehicle batteries need a lot of electricity as power to ensure the safety of the driving process. After being placed for a certain period of time, the power battery will gradually accumulate water and air to gradually increase its internal temperature, which will lead to spontaneous combustion or explosion of the battery. Therefore, the power battery should be a safer battery, but the safety problem is particularly important due to its product characteristics. Because of its own power properties, power electric vehicles require their batteries to get a lot of power in a short period of time, charge them for a long time, and then store them for a long period of time for cycling, thus effectively ensuring the safety of the batteries. However, due to its long-term use, it will produce a certain degree of electrochemical phenomenon, which will affect the safety.

What are its advantages in terms of security?

When the lithium iron phosphate battery is used for charging, the internal structure of the cell changes during charging and discharging because of its own structure with certain conductivity. Such changes will release more energy. This allows the lithium iron phosphate battery to achieve a lower temperature during the charging process, and there is no need to worry about the thermal explosion of the battery during use. Because of its good heat dissipation capacity, it has no impact on the use of high-temperature environment, which is also the reason why it is welcomed by many enterprises. Also, because the lithium iron phosphate battery has excellent safety protection performance, it will not produce explosion. This makes it have greater advantages in terms of security.
