Briefly describe the cycle life of ternary lithium battery packs

by：Vglory 2021-03-24

The theoretical life of a ternary lithium battery is about 800 cycles, which is medium among commercial rechargeable lithium batteries. Lithium iron phosphate is about 2,000 cycles, while lithium titanate is said to be able to reach 10,000 cycles. At present, mainstream battery manufacturers promise more than 500 times in the specifications of their processed ternary batteries. The life of a ternary lithium battery is determined by the number of cycles of the battery, and the capacity of a ternary lithium battery pack will continue to decay as the number of charging and discharging increases. In the relevant laboratory, the ternary lithium battery was continuously charged and discharged at a charge-discharge rate of 1C. After 1,000 charging cycles, the battery capacity dropped to 80% of the new battery state. Regarding the new energy vehicle lithium battery, its life is important to calculate the cycle life by the number of cycles that the battery overflows. Generally speaking, the service life of the ternary lithium battery pack is only about 6 to 10 years. Among the new energy passenger cars, most models have begun to use ternary lithium battery packs. Although BYD still uses lithium iron phosphate batteries as the main battery, it is also accelerating to ternary batteries as the market changes. The direction of the use and research of lithium battery packs. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
