What is the reason why the customized capacity of lithium batteries is declining faster and faster?18650 lithium battery 3.7 v

release time:2023-09-08 Hits: Popular:AG11 battery

　　The activity of lithium ions also decreases, which will lead to an increase in their resistance value and then affect the attenuation of battery capacity. In fact, from a practical environment perspective, it will affect the decline of the battery, including the voltage of charging and discharging, and even the power of charging and discharging, as well as the temperature of the environment.

　　At present, the main use of new energy vehicle batteries is ternary lithium batteries. Therefore, the characteristic of ternary lithium batteries is that they are afraid of high environmental temperatures, which can affect their service life. Of course, this also affects energy density, in terms of the power rate of electric vehicles.

　　The main reason for battery decline is that vehicles use different charging and discharging rates to meet different driving conditions during use. The higher the charging and discharging rate, the faster the battery capacity decays. In fact, it is also mainly due to changes in the structure and properties of materials, which makes the internal ion diffusion relatively difficult.

　　For batteries, if the internal resistance is inconsistent, it will result in uneven distribution of current and voltage within them, which can lead to undervoltage of individual batteries locally. Overall, there are many factors that affect the lifespan of power battery packs, and of course, all of them are also interdependent.
