The most comprehensive description of lithium batteries, the ten advantages of lithium batteries for electric vehicles!

Electric vehicle batteries are divided into lead-acid batteries and lithium-ion batteries. Compared with lead-acid batteries of electric vehicles, we know less about lithium-ion batteries of lithium-ion electric vehicles. Let's briefly introduce the ten advantages of lithium-ion batteries.

1. Long cycle life: the lithium-ion battery is charged and discharged at a rate of 1C. Its cycle life is more than or equal to 500 times. The capacitance at the 500th time is more than 70% of the nominal copper beam. However, if the ordinary lead-acid battery is discharged at 0.5 and charged at 0.15C, its cycle life is less than or equal to 350 times, and its capacitance is less than or equal to 60%.

2. Good discharge performance at low temperature: the lithium-ion battery can work normally at - 25 ℃, and its capacitance can reach 70% of the nominal capacity, while the ordinary lead-acid battery can work normally at - 10 ℃, and not at - 25 ℃.

3. Strong charge retention ability: when a fully charged lithium-ion battery pack is placed for two months, its electric capacity is greater than or equal to 80%. The normal lead-acid battery is only 40% - 50% of the nominal capacity when it is placed for two months.

4. Strong continuity ability: because the weight of lithium-ion battery pack is only 30% of that of ordinary lead-acid battery, the continuity ability of lithium-ion battery is strong under the same voltage and capacitance.

5. High specific energy: because the volume of lithium-ion battery is only 30% of that of ordinary lead-acid battery, the energy reserve of lithium-ion battery is larger than that of ordinary lead-acid battery when using the same space.

6. Wide operating temperature range: lithium-ion battery can work in the range of - 25 degrees to 55 degrees, while lead-acid battery can only work in the range of 10 degrees to 40 degrees. But ordinary lead-acid batteries can only work in the range of 10 degrees to 40 degrees.

7. Short charging time: due to the large current charging characteristics of lithium-ion batteries, the charging time is only 4-5 hours, while ordinary lead-acid batteries need 8-10 hours.

8. High environmental protection performance: compared with ordinary lead-acid battery, which has a lot of heavy metal lead harmful to human body and environment, lithium-ion battery is a high environmental protection product.

9. It can discharge in large current: the capacity of lithium-ion battery is only 60% of the rated capacity under 1C power.

10. High current discharge does not affect the cycle life: high current discharge at 1.5C rate has no effect on the cycle life of lithium-ion battery. However, the cycle life of ordinary lead-acid battery is only 30% - 40% of the nominal cycle life when it is discharged at 1.5C.
