Introduction to the performance characteristics of ternary lithium-ion batteries

1. Ternary lithium-ion batteries are much smaller and lighter in weight than ordinary batteries. Generally, a lithium-ion battery of the same model is only half the size of a battery and weighs one-third of the battery. 2. The lifespan of ternary lithium-ion batteries is generally about 5 to 6 years, and the warranty period is generally about three years, which is much longer than that of ordinary batteries, which only have one year or one and a half years. Change the battery. 3. Ternary lithium ion batteries are safer than ordinary batteries. Lithium ion batteries are qualitatively different from other ordinary batteries. They will not explode when subjected to heavy pressure, impact, short circuit, etc. 4. The ternary lithium-ion battery is greener than the ordinary battery, and has little environmental pollution, because the long service life can prevent the pollution to the environment caused by the replacement of ordinary batteries. 5. When consumers are charging ordinary lead-acid batteries, they have always been worried about the memory effect of the battery. When a ternary lithium-ion battery is used, everyone can breathe a sigh of relief. The lithium-ion battery does not have a memory effect and has a long cycle life. 1. The energy density of the battery is high. The energy density of a battery is the electric energy released by the average unit volume or mass of the battery. The greater the energy density of the battery, the more electricity stored per unit volume. BYD's lithium iron phosphate battery has a single energy density of 150Wh/kg, and BYD's ternary lithium-ion battery has an energy density of 200Wh/kg. 2. Good cycle performance. The theoretical life of a ternary lithium-ion battery is 2000 charge-discharge cycles, but in actual use, after 900 charge-discharge cycles, the battery capacity basically decays to 55%. But if each battery charge and discharge are controlled to work in a 0%-50% or 25%-75% cycle, even after 3000 charge and discharge cycles, the battery capacity can basically be maintained at about 70%. But this also requires an excellent battery management system. The theoretical cycle life of lithium iron phosphate batteries is more than 2000 times, but the actual use is about 500 times. However, lithium iron phosphate batteries have a fatal shortcoming, that is, poor low-temperature performance, even if they are nano-sized and carbon coated, this problem has not been solved. Studies have shown that a battery with a capacity of 3500mAh, if it is operated at -10°C, after less than 100 charge-discharge cycles, the power will decay sharply to 500mAh, which is basically scrapped. So in the north, the working conditions of this battery are really worrying. 3. Long battery life. According to the calculation of the battery cycle of Sanyuanli 1000 times, it is fully charged and discharged once in three days, and the service life reaches 8.3 years. Even if there is a loss process, it can also reach more than 7 years. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
