Analysis of the characteristics of lithium batteries for electric vehicles

1. Long cycle life The lithium battery is charged and discharged at a rate of 1C with a cycle life greater than or equal to 800 times, and the capacity at the 800th cycle is greater than 70%. And even if the lead-acid battery is discharged at 0.5 and charged at 0.15C, its cycle life is less than or equal to 350 times, and the capacity is less than or equal to 60%. 2. Light weight, small size and long battery life. Compared with lead-acid batteries of the same capacity on the market, lithium batteries are 2/3 of the volume of lead-acid batteries and weigh about 1/3 of the weight of lead-acid batteries. Lithium batteries of the same volume have a higher capacity than lead-acid batteries, and the reduction in weight increases the battery life of electric vehicles by about 10%. 3. The working temperature range is large. It is generally found that the general lead-acid battery has poor temperature adaptability, especially in winter, the cruising range is greatly affected, while the lithium battery can work normally between minus 25 degrees and minus 40 degrees without affecting Life and mileage. Fourth, no memory effect, strong charge retention ability. After being placed for two months, the electric capacity of a lithium battery pack that is overflowing will be greater than or equal to 95%, while the lead-acid battery is only 40% of the nominal capacity after being placed for two months- 50%. 5. The country advocates green environmental protection products. Compared with lead-acid batteries which have a large amount of heavy metal lead that is harmful to the human body and the environment, lithium batteries are highly environmentally friendly products and do not contain heavy metals such as lead, mercury, and cadmium.
