Why do power lithium batteries not have to blindly follow the trend in pursuit of high energy density?
With the development trend of new energy vehicles, power 2025 button cell battery technology is also constantly improving. At present, the unit specific energy of lithium iron phosphate battery is 160wh/kg, and the system specific energy can reach 130. The unit specific energy of 18650 using NCA system has reached 240Wh/kg, and the system specific energy has reached 150Wh/kg. In addition to the increasing power policies and regulations, the reduction in subsidies has also resulted in more stringent cost regulations for power 2025 button cell battery companies. How companies choose to become processing manufacturing industries has received much attention. The new energy vehicle manufacturing industry should not only attach great importance to the density of rechargeable lithium batteries, but also integrate the lightweight of the car body and reduce energy consumption. The unique energy of power lithium batteries is closely related to the safety factor. The higher the energy, the higher the safety level standards. At present, the pursuit of perfect rechargeable battery energy ratio cannot be directly improved, and the policy does not need to stimulate mileage too much. .
How to ensure a balance between automotive performance and safety of power lithium batteries?
There are many ways to improve the mileage of new energy vehicles. The most direct way is to increase the output power of rechargeable batteries and increase the output power of rechargeable batteries.
The key to improving the specific energy of power lithium batteries is the nickel component in the cathode material of the rechargeable battery. The higher the nickel content, the higher the specific energy of the driving 2025 button cell battery, and the worse the reliability of the rechargeable battery. The heating of the rechargeable battery The greater the chance that it cannot be manipulated. 2025 button cell battery manufacturing companies must strictly control the nickel in 2025 button cell battery raw materials so that perfectionists can achieve high-efficiency energy with relatively low density and low cost. They do not need to blindly follow the crowd and increase the nickel content. The key is to grasp the safety factor, not the more important performance. , related car teams, it is best to reduce vehicle mileage in terms of vehicle and maintenance quality, rather than simply adding batteries to increase mileage.
The general trend of ternary batteries is that in 2017, when the total output of lithium-ion batteries reached 100 million watt-hours, it increased by 33% year-on-year. However, compared with the 150 equipment companies in 2017, the number of companies has dropped to less than 100. The trend of high efficiency energy density has become the trend of the development of 3D batteries. With the increase in national subsidies and the improvement of power and energy management and control, enterprises should continue to improve their technical level. New Energy Development Technology Co., Ltd. released two new products: new energy buses. The sales volume of special-purpose vehicles is 135ah. The three-dimensional square aluminum shell 2025 button cell battery has an energy density of 215wh/kg and a cycle life of 3000 times. The sales volume of special-purpose vehicles is 115ah 2025 button cell battery, respiratory system service life is 10,000. The unique energy of power lithium batteries is the most vivid mileage indicator. By 2020, the power engineering ratio of a lithium-ion battery will be 350wh/kg, and a new new energy vehicle will have the same physical strength as a fuel vehicle. Based on the current intelligent management of 2025 button cell battery materials and technological development trends, new 2025 button cell battery packaging technology is used to achieve systematic energy comparison.
However, compared with the Kangjiagang batteries currently used by Tesla, the specific energy of domestic power lithium batteries is still very different, and the safety performance and consistency of the product need to be improved. Therefore, in China, 2025 button cell battery companies should attach great importance to improving product safety performance, rather than blindly following the trend in pursuit of perfect, sound and efficient power energy density and wind speed to avoid production safety accidents.
