What is the actual cycle life of a ternary lithium battery? With the continuous rise of the international population and the continuous development of global science and technology, the use of non-renewable energy is increasing, and the current resources are gradually facing a stage of scarcity. In order to maintain the earth's environment on which mankind temporarily depends for survival, the maintenance of resources is the most important. Therefore, energy-saving and environmentally-friendly products are spreading more and more everywhere, such as the battery market. Lithium batteries are quickly occupying some markets due to their long life, low maintenance cost, low self-discharge rate, light weight, and high voltage, and are gradually replacing lead-acid batteries. So in what aspects is the ternary lithium battery widely used? How long is the life cycle? The three major advantages of ternary lithium battery packs: high-voltage channels. The voltage channel is an important indicator of battery energy density and determines the basic efficiency and cost of the battery. The higher the voltage channel, the larger the specific capacity. The battery with the same size, components, or even the same ampere hour, the voltage channel has a longer battery life distance than the ternary lithium battery. The ternary data voltage channel is significantly higher than that of lithium iron phosphate, the high-voltage line voltage can reach 4.2 volts, and the discharge channel can reach 3.6 or 3.7 volts. 3. High energy density and high vibration density (vibration density refers to the mass per unit volume measured after the powder in the container is vibrated under specified conditions). Now, Beijing New Energy, Jianghuai, Jiangling, and Chery have been listed on new energy buses, and most models have begun to choose ternary lithium batteries. BYD, although it is still dominated by lithium iron phosphate batteries, it follows the changes in market trends. It is also to accelerate the discussion on the direction of using ternary lithium battery packs. The company recently stated that the investor interaction channel, in the future new passenger vehicles, the company will begin to use ternary lithium batteries, and at the same time, it is also vigorously increasing its development. Explore. Another example is the Model (Ministry of Industry and Information Technology) Road Motor Vehicle Processing Company and Product Announcement issued by the Ministry of New Energy Industry and Information Technology in 103 (approved in 285). A total of 71 selected internal-lithium batteries, accounting for 69% of the total. , Higher than the 62% in 2015. Lithium batteries have also become the main batteries for a new batch of electric special vehicles. Disclaimer: Some pictures and contents of articles published on this site are from the Internet.
