Lead-acid batteries used in traditional electric vehicles will produce a lot of pollution and lead vapor after being discarded. According to statistics, a group of waste batteries of electric vehicles will pollute tens of thousands of tons of water. Lead is not easy to be excreted from the body, but also can cause metabolic, reproductive and neurological diseases. Once the body's lead content exceeds the standard, it will lead to mental retardation, fetal malformation, easily induce malignant tumors in children, and even lead to death.
Compared with lead-acid batteries, lithium batteries have a natural advantage in environmental protection. The materials used in lithium batteries do not contain harmful heavy metals such as cadmium, lead and mercury. There are no pollutants in the production and use of lithium batteries, which protect human health. The problem of polluting water and soil in the recycling process of waste batteries is solved.
In addition, lithium batteries also have the advantages of high specific energy, long cycle life, low self-discharge rate, no memory effect and so on. Lithium batteries have a high energy storage density, which is 460-600Wh/kg, about 6-7 times that of lead-acid batteries. Their service life can reach more than six years. Lithium ferrous phosphate batteries are charged and discharged with 1CDOD and can be used for 10,000 times. Lithium ferrous phosphate batteries have high power endurance, including lithium-ion lithium-ion batteries for electric vehicles. The battery can reach 15-30C charging and discharging capacity, which is convenient for high-strength start-up and acceleration; the self-discharge rate is very low, generally less than 1%/month, less than 1/20 of the nickel-hydrogen battery; lithium battery can completely meet the needs of vehicle power, coupled with its green, environmental protection features, has become an ideal product for electric vehicle applications.
