With the popularization of electric vehicles, more and more people use electric vehicles, and with it, there are more and more used batteries for electric vehicles. It is predicted that the cumulative amount of domestic power batteries will be about 2 in 2015. 10,000 to 40,000 tons, by 2020, China's electric vehicle power battery cumulative scrap will reach 120,000 to 170,000 tons. If there is no standardized battery recycling system, these batteries will undoubtedly cause great harm to the environment.
Although the electric vehicle is zero-emission, the waste battery generated by it is very polluted. Wu Feng, a professor at Beijing Institute of Technology, said that a 20-gram Mobile Phone battery can pollute the water of three standard swimming pools. If it is abandoned on the land, It can pollute 1 square kilometer of land for about 50 years. Imagine if a 200 kilogram electric vehicle power battery was abandoned in the natural environment? A large amount of heavy metals and chemicals entering nature will cause greater pollution to the environment.
At present, the research on domestic power batteries is mainly focused on improving performance, and the attention to recycling is obviously insufficient. A complete vehicle power battery recycling system has not yet been established. This makes people very worried. Many people have called for clean and environmental protection to be the general trend of motor vehicle development in the future, and electric vehicles can achieve zero emissions, which is very helpful for environmental protection, but the choice of batteries and the later harmless treatment. It is important to avoid creating new environmental pollution. Battery recycling for electric vehicles is imminent.
