Why More And More People Choose Lithium Batteries

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

2. long service life, which can reach more than 6 years. The battery 1C (100%dod) with lithium ferrous phosphate as the positive pole is charged and discharged, with a record of 10000 times of use

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. 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 startup and acceleration;

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

6. light weight, about 1/5-1/6 of lead-acid battery products under the same volume

7. it has strong applicability to high and low temperature, and can be used at -20 ° C-60 ° C. after processing, it can be used at -45 ° C.

8. It is green and environmentally friendly. It does not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium, regardless of production, use and scrap.

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 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).
