The main advantages of lithium batteries are：
1. The service life is long, and the service life can reach more than 6 years. The battery with lithium iron phosphate as the positive electrode is charged and discharged with 1 CDOD, and it has a record of 10,000 times of use;
2. The specific energy is relatively high. It has a high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries;
3. It has high power tolerance, among which 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;
4. The rated voltage is high (the working voltage of a single unit is 3.7V or 3.2V), which is approximately equal to the series voltage of 3 NiCd or NiMH 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 that of lead-acid products;
6. The production basically does not consume water, which is very beneficial to our country which is short of water.
7. High and low temperature adaptability, can be used in the environment of -20 ℃ - 60 ℃, and can be used in the environment of -45 ℃ after technical treatment;
8. The self-discharge rate is very low, which is the best for this battery One of the outstanding advantages, at present, it can generally achieve less than 1% per month, which is less than 1/20 of nickel-metal hydride batteries;
9. Environmental protection, regardless of production, use and scrap, does not contain or produce any lead, Mercury, cadmium and other toxic and harmful heavy metal elements and substances. 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), L is liter (volume unit).
