Why do more and more people choose lithium batteries?

source: release time:2019-04-19 Click volume:386

1. The energy ratio is relatively high. With high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times of lead-acid battery;

2. Long service life, service life can reach more than 6 years, lithium iron phosphate is the positive battery 1C (100% DOD) charge and discharge, there are records that can be used 10,000 times

3. The rated voltage is high (the single working voltage is 3.7V3.2V), which is equal to the series voltage of three nickel-cadmium or nickel-hydrogen rechargeable batteries, which is convenient for forming the battery power pack;

Why do more and more people choose lithium batteries?

Gold battery


4. With high power bearing capacity, lithium iron phosphate lithium ion battery for electric vehicles can achieve 15-30C charge and discharge capacity, which is convenient for high-intensity start-up acceleration;

5. The self-discharge rate is low, which is one of the most outstanding advantages of the battery. At present, it can generally be 1%/month, which is much lower than 25-30% of Ni-Cd, 30-35% of Ni and MH. .

6. Light weight, the weight in the same volume is about 1/5-1/6 of lead-acid battery products.

7. High and low temperature applicability, can be used in the case of -20 ° C -60 ° C, can be used in the -45 ° environment after the process.

8. Green and environmental protection, no matter whether it is produced, used or scrapped, does not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium.

9. Production basically does not consume water, which is very beneficial to China lacking water.

10. Specific energy refers to the energy per unit weight or unit volume.

The specific energy is expressed by Wh/kg or Wh/L. Wh is the unit of energy, W is watt, h is hour; kg is kilogram (weight unit), and L is liter (volume unit).

So more and more people choose to use lithium batteries.
