Ten Cold Knowledge Of Lithium Battery

Briefly introduce the ten advantages of lithium-ion batteries. What are the benefits of lithium batteries for electric vehicles?

1. Long cycle life:

The lithium-ion battery is charged and discharged at a rate of 1C, and its cycle life is greater than or equal to 500 times, and the electric capacity at the 500th time is greater than 70% of the nominal copper beam. Even if the 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 electric capacity is less than or equal to 60%.

2. Good discharge performance at low temperature:

Lithium-ion batteries can work normally at -25 degrees, and their electrical capacity can reach 70% of the nominal capacity, while lead-acid batteries can do 50% of the electric capacity at -10 degrees.

3. Strong charge retention ability:

After the fully charged lithium ion battery pack is placed for two months, its electric capacity is greater than or equal to 80%, while the lead acid battery is placed for two months, only 40% -50% of the nominal capacity.

4. Strong continuity:

Since the weight of a lithium-ion battery pack is only 30% of that of a lead-acid battery, the lithium-ion battery has a strong continuity at the same voltage and capacity.

5. High specific energy:

Since the volume of a lithium-ion battery is only 30% of that of a lead-acid battery, the energy reserve of the lithium-ion battery is larger than that of a lead-acid battery when using the same space.

6. Wide operating temperature range:

Lithium ion batteries can work in the range of -25 degrees to 55 degrees, while lead-acid batteries can only work in the range of 10 degrees to 40 degrees.

7. Short charging time:

Because the lithium ion battery has the characteristics of large current charging, the charging time is only 4-5 hours, while the lead-acid battery requires 8 to 10 hours.

8. High environmental protection performance:

Compared with lead-acid batteries which have a large amount of heavy metal lead which is harmful to human body and environment, lithium-ion batteries are highly environmentally friendly products.

9. Can discharge with large current:

Lithium-ion battery discharges at high current at 1C rate, and its capacity is only 60% of the rated capacity.

10. High current discharge does not affect cycle life:

Lithium-ion batteries discharge at a current of 1.5C at a high current, which has no effect on their cycle life. The lead-acid battery discharges at a high current of 1.5C. Its cycle life is only 30% -40% of the nominal cycle life.
