Why do more and more users choose lithium batteries

The use of lithium batteries can no longer be widely described. It is very extensive. Then why do more and more people choose lithium batteries? Do you know?

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

2. The service life is long, and the service life can reach more than 6 years. The battery 1C (100% DoD) with lithium ferrous phosphate as the positive electrode is charged and discharged, and there is a record that it can be used for 10000 times

3. The rated voltage is high (the single working voltage is 3.7v3.2v), which is about equal to the series voltage of three nickel cadmium or nickel hydrogen rechargeable batteries, so as to form a battery power pack;

4. It has high power bearing capacity, in which the lithium ferrous phosphate lithium-ion battery for electric vehicles can reach the charging and discharging capacity of 15-30c, which is convenient for high-intensity start-up and acceleration;

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

6. Light weight. The weight under the same volume is about 1 / 5-1 / 6 of that of lead-acid battery products

7. It has strong applicability to high and low temperature, and can be used at - 20 ° C-60 ° C. After process treatment, it can be used at - 45 ° C.

8. Green environmental protection. No matter in production, use or scrap, it 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, which is short of water.

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

The specific energy is expressed in WH / kg or WH / L. Wh is the unit of energy, W is watt and H is hour; Kg is the kilogram (weight unit) and l is the liter (volume unit).
