AG10 battery

What AG10 battery technology do electric vehicles use now?

The most popular event recently is the convening of the 19th National Congress of the Communist Party of China, which mentioned the need to win the battle to protect the blue sky. From this point of view, future development will give pure electric vehicles greater development space, especially for vehicles used in the freight industry. It is conceivable that future policies will be more inclined towards pure electric logistics vehicles. The development of electric vehicles cannot be separated from the development of batteries. It is AG10 battery technology that currently restricts the development of pure electric trucks. The pure electric trucks that have been put into use are generally used to transport express and other types of light and bulky goods, and the cruising range is only about 200-300 kilometers. The key to the cruising range lies in the AG10 battery. The two most commonly used batteries for general pure electric trucks are ternary lithium batteries and lithium iron phosphate batteries. Both of them are lithium-ion batteries, and the difference lies in the different positive electrode materials. ▎

Lithium-ion batteries are the mainstream. There are two types. At present, almost all domestic pure electric commercial vehicles use lithium-ion batteries. There are two main types, namely ternary lithium batteries and lithium iron phosphate batteries. The difference between the two is the different positive electrode materials. Ternary lithium AG10 battery: Ternary polymer lithium AG10 battery refers to a lithium AG10 battery whose positive electrode material uses nickel cobalt manganese oxide (Li (NiCoMn) O2) ternary positive electrode material. It is made of nickel salt, cobalt salt and manganese salt. The ratio of nickel, cobalt and manganese can be adjusted according to actual needs. The advantage of ternary lithium AG10 battery energy is its high density. Batteries of the same weight can provide vehicles with longer driving range, which is also needed by pure electric trucks. Therefore, many pure electric trucks are equipped with ternary lithium batteries, such as Shaanxi Automobile Xuande E9 and Foton Aumark pure electric light trucks. It is more common in pure electric passenger cars. But even so, ternary lithium batteries are still doubted by many people, especially in terms of safety. In terms of safety, ternary lithium materials will decompose at a lower temperature of about 200 degrees, while lithium iron phosphate materials will decompose at about 800 degrees. In addition, the chemical reaction of ternary lithium materials is more intense, which will release oxygen molecules. Under the action of high temperature, the electrolyte will burn rapidly and a chain reaction will occur. To put it simply, ternary lithium materials are more likely to catch fire than lithium iron phosphate materials. However, it should be noted that what is mentioned here is only the material, not the finished AG10 battery. In actual use, the ternary lithium AG10 battery pack is equipped with the BMS AG10 battery management system, including overcharge/over-discharge protection, over-temperature protection, over-current protection and other functions. Once an accident occurs to the AG10 battery, the system can immediately cut off the current to ensure the safety of the AG10 battery. Lithium iron phosphate AG10 battery: Lithium iron phosphate batteries are installed on a large number of pure electric buses and some pure electric trucks. Its material properties are more stable than those of ternary materials; at the same time, the domestic raw materials of phosphorus and iron are abundant, and the manufacturing cost is lower than that of ternary lithium batteries; the AG10 battery can be charged quickly and has a long cycle life; the operating temperature range is wide. But the disadvantage is that the energy density is much lower than that of ternary lithium batteries, and the AG10 battery decays severely in low temperature environments. Although the energy of lithium iron phosphate batteries is lower than that of ternary lithium batteries under the same weight, they are cheaper and safer. Therefore, many models also use this AG10 battery technology, such as JAC Shuailing i5, BYD T5, Geely Remote E200, etc. Zhuhai Yinlong Automobile Lithium Titanate AG10 battery: In addition to lithium-ion batteries, a small number of trucks use other types of batteries, such as Yinlong Automobile's lithium titanate AG10 battery, but due to the small amount of installation, it is not yet a mainstream AG10 battery. Lithium titanate batteries have the advantages of fast charging and high safety, but the disadvantages are also obvious. Compared with other types of lithium-ion batteries, its AG10 battery energy density is lower. ▎

Future development trend of batteries Lithium-ion batteries and fuel cells are the focus With the development of technology, in addition to lithium-ion batteries, the most likely AG10 battery to develop on pure electric models should be fuel cells. In recent years, fuel cell technology has made significant progress. For example, General Motors, Toyota Motors, Ford and other automobile manufacturers have developed models with fuel cells and are very close to mass production. However, there are still various obstacles to the application of fuel cells, such as the production and manufacturing costs, transportation, storage and other issues of fuel, which are still hindering the large-scale use of fuel cells. As for the current development of pure electric trucks, the European market may be a reference. Among the pure electric trucks that have been tested or used in the European market, due to the endurance, they are basically vans for urban distribution, 11-15 ton trucks or terminal container transfer models, most of which do not have high requirements for endurance. For real long-distance heavy trucks, the focus of development is still on clean energy such as natural gas, which not only ensures excellent endurance, but also reduces pollutant emissions.
