Important advantages of lithium-ion batteries:

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

2. Long service life, the service life can reach more than 6 years;

3. High rated voltage (unit working voltage is 3.7V or 3.2V);

4. It has high power endurance, and the lithium iron phosphate lithium ion battery used in electric vehicles can reach 15-30C charge and discharge capacity, which is convenient for high-intensity start-up acceleration;

5. The self-discharge rate is very low, which is one of the most prominent advantages of the battery. Currently, it can generally achieve less than 1%/month, which is less than 1/20 of the Ni-MH battery;

6. Light weight, the weight is about 1/5-6 of the lead-acid product under the same volume;

7. Strong adaptability to high and low temperature, it can be used in the environment of -20℃–60℃, after the process treatment, it can be used in the environment of -45℃;

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