What are the factors that affect the service life of ternary lithium batteries?

As for what factors will affect the service life of ternary lithium-ion batteries, Hydrogen Cloud Chain believes that this should be analyzed from the structure and application of the battery itself, such as battery materials, operating environment and best working conditions. Specifically, in the process of use, due to improper use, an irreversible electrochemical reaction within the lithium-ion battery will cause the capacity to decrease, such as the decomposition of the electrolyte inside the battery and the loss of activity of the active materials inside the battery. Directly lead to a sharp decline in the life of the ternary lithium ion battery. Of course, the end of the service life of the lithium battery of the electric car power does not mean that the battery cannot be charged or discharged, but that the discharge capacity of the battery at this time is relatively lower than that of the new battery. If you continue to use it, it will bring users Poor car experience. Because the power lithium battery service life specification was formulated a few years ago, at that time the battery capacity was small, and the electric car had a short driving journey, which attenuated to less than 80% of the new battery. It really felt that the driving journey was much shorter. For example, if the continuous journey is 200 kilometers, the battery is attenuated to 80%, and the battery will be charged for 160 kilometers. Now the continued journey of electric cars is higher, and the 20% attenuation is not so great for users.
