The advantages of lithium batteries are mainly:
1. The service life is long, the service life can reach more than 6 years, and the battery with lithium iron phosphate as the positive electrode is charged and discharged with 1CDOD, and there are records that can be used 10,000 times;
2. It is higher than the energy. With high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times of lead-acid battery;
3, with high power bearing capacity, which lithium iron phosphate lithium ion battery for electric vehicles can achieve 15-30C charge and discharge capacity, easy to start high-intensity acceleration;
4, the rated voltage is high (the single working voltage is 3.7V or 3.2V), which is equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries, which is convenient for forming a battery power pack;
5, light weight, the weight of the same volume is about 1/5-6 of lead-acid products;
6. Production basically does not consume water, which is very beneficial for China lacking water.
7, high temperature and low adaptability, can be used in the environment of -20 Â° C -60 Â° C, after the process of processing, can be used in -45 Â° C environment;
8, the self-discharge rate is very low, this is one of the most outstanding advantages of the battery, currently can generally achieve 1% / month, less than 1 / 20 of nickel-hydrogen batteries;
9. Green and environmental protection, no matter whether it is produced, used or scrapped, does not contain any toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium.
Note: 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, h is hour; kg is kilogram (weight unit), and L is liter (volume unit).
