The lead-acid batteries used in traditional electric vehicles can cause significant pollution and lead vapor when discarded. According to statistics, a group of discarded batteries from electric vehicles can contaminate tens of thousands of tons of water. Lead is not easily excreted from the body and can also cause metabolic, reproductive, and neurological diseases in the human body. Once the lead content in the human body exceeds the standard, it can lead to intellectual decline, fetal malformation, and easily induce malignant tumors in children, even leading to death.

Compared to lead-acid batteries, lithium batteries have natural advantages in terms of environmental protection. The materials used in lithium batteries do not contain harmful heavy metal substances such as cadmium, lead, mercury, etc. Lithium batteries do not produce pollutants during production and use, ensuring human health. The problem of polluting water sources and soil during the recycling process of waste batteries is also easily solved.

In addition, lithium batteries also have advantages such as high specific energy, long cycle life, low self discharge rate, and no memory effect. Lithium batteries have high energy storage density, currently reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries; The service life can reach more than 6 years, and batteries with lithium iron phosphate as the positive electrode can be charged and discharged with 1CDOD, with a record of 10000 uses; Capable of withstanding high power, the lithium iron phosphate lithium-ion battery used in electric vehicles can achieve a charge and discharge capacity of 15-30 ° C, facilitating high-intensity acceleration during start-up; The self discharge rate is very low, currently generally below 1% per month, less than 1/20 of nickel hydrogen batteries; Lithium batteries are fully capable of meeting the power needs of vehicles, and with their green and environmentally friendly characteristics, they have become an ideal product for electric vehicle applications.
