Is the power lithium-ion battery safe? Will it pollute the environment?

Is the power lithium-ion battery safe? Is there pollution? Is the battery of a new energy vehicle safe? I am going to buy a new energy vehicle to deter trouble, just a dozen days ago. According to foreign media reports, a stolen Tesla electric car collided with other vehicles during the police chase, and the lithium battery was split into two. After several years of development, new energy vehicle power lithium-ion battery technology has made great progress. The battery and materials themselves have flame-retardant technology, and the risk of fire is greatly reduced. Xu Yanhua, deputy secretary-general of the my country Association of Automobile Manufacturers, said that, like traditional cars, the magnetic poles will not be cleaned and blasted. When people think of power lithium-ion batteries, they usually think of lead batteries used on electric bicycles. The recall of unqualified lead batteries is accused of causing heavy metal pollution. So will electric vehicle batteries bring new pollution? The power lithium-ion batteries of new energy vehicles have passed strict national tests, and all chemical substances can be recalled. Li Yunfei, a spokesman for BYD Auto said. Compared with electric bicycle batteries, the threshold for recycling new energy vehicle batteries is higher, and they are generally recycled by automobile companies themselves, but standard recycling still requires supporting policies and regulations. The mileage of a pure electric vehicle is 35% lower than in cold weather. In cold weather, it dropped by 57%, which is less than half of the normal range. Battery capacity: The battery capacity of electric vehicles is usually measured in kilowatt hours (KWH). The larger the battery pack capacity, the stronger the car's energy storage capacity, and the greater the pure electric driving range. Driving distance: The driving distance refers to the maximum driving distance of the vehicle after it is fully charged, but this value is for reference only. Factors such as driving mode, climate, and how many electric devices are driven will affect the driving distance of an electric vehicle. Among them, the driving style is relatively steep, use electric equipment as little as possible, and it is very helpful to add a series of electric vehicles, which is also applicable to traditional powered vehicles. However, the impact of hot and cold weather on the mileage of electric vehicles is far greater than that of traditional cars. Research tests show that in hot weather, the mileage of pure electric vehicles is 35% lower than in cool weather. In cold weather, it dropped by 57%, which is less than half of the normal range. Battery capacity: The battery capacity of electric vehicles is usually measured in kilowatt hours (KWH). The larger the battery pack capacity, the stronger the car's energy storage capacity, and the greater the pure electric driving range. However, the addition of the battery pack is bound to increase the quality of the vehicle, affect the performance of the vehicle, and greatly increase the processing cost. How to balance the distance, the number of battery packs, and the processing cost has become a difficult problem for the development of electric vehicles.
