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 Battery 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 storage capacity, the Lithium Polymer 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 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 advantageous for China's water shortage.
7, high temperature and low adaptability, can be used in the environment of -20 ° C -60 ° C, after the process of processing, can be used in -45 ° 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, 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 of weight or volume. Specific energy is expressed as Wh/kg or Wh/L. Wh is the unit of energy; W is watt; h is hour; kg is kilogram (unit of weight) and L is litre (unit of volume).
