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 batteries;

2. 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 at 1C (100% DOD), and there are records that it can be used 10,000 times;

　　3. The rated voltage is high (the single working voltage is 3.7V or 3.2V), which is approximately equal to the series voltage of three nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient for forming a battery power pack;

　　4. With high power endurance, in which the lithium iron phosphate lithium battery for electric vehicles can reach 15-30C charge and discharge capacity, which is convenient for high-intensity startup acceleration;

　5. The self-discharge rate is very low, which is one of the most prominent advantages of the battery. At present, it can generally be less than 1% / month, which is less than 1/20 of the nickel-hydrogen battery;

　6. Light weight, the weight is about 1 / 5-6 of lead acid products under the same volume;

　　7. High and low temperature adaptability, can be used in the environment of -20 ℃ --60 ℃, after processing, can be used in the environment of -45 ℃;

　8. Green and environmental protection, regardless of production, use and scrap, does not contain or produce any toxic and hazardous heavy metal elements and substances such as lead, mercury, cadmium.

　9. The production basically does not consume water, which is very beneficial for China, which lacks water.
