With the popularization of electric vehicles, electrical batteries recycling and reuse have become a topic of concern to many netizens. Netizen Simon Rock said: Clean and environmental protection is the general trend in the development of motor vehicles in the future, and electric vehicles can achieve zero emissions, which is of great help to environmental protection. However, the selection of electrical batteries and subsequent harmless treatment is particularly important, and in new environments, pollution should be prevented. Industry experts pointed out that as an important part of the new energy vehicle industry chain, while the development of power li ion battery improves performance, the exploration of recycling and reuse modes is also an issue that cannot be ignored.
A 20-gram cell phone battery can pollute the water of three standard swimming pools. If it is discarded on the ground, it can pollute 1 square kilometer of land for about 50 years. Just imagine, what if 200 kilograms of lithium battery for electric cars are discarded in the natural environment? A large number of heavy metals and chemical substances entering nature will cause greater pollution to the environment.
At present, the research of power li ion battery in some countries mainly focuses on improving performance, and there is obviously insufficient attention to the recycling link. At present, li ion battery is widely used in electric vehicles. This battery does not contain heavy metal elements harmful to the environment such as mercury, cadmium, and lead, but its anode and cathode materials, electrolyte solutions, and other substances have a great impact on the environment. If there is no standard electrical batteries recycling system, these batteries will undoubtedly do great harm to the environment.
Generally, the service life of li ion battery in the general environment is about 20 years, but when used for vehicle power, if the battery capacity attenuates to less than 80% of the initial capacity, the driving range of the electric vehicle will be significantly reduced. Therefore, the actual service time is about 3-8 years.
However, these waste electrical batteries still have utilization value. Batteries with a capacity of less than 80% can continue to be used for energy storage in the power grid. It can also be a power source for low-speed vehicles such as electric field vehicles and have secondary utilization value. Echelon utilization can give full play to the value of power li ion battery, so as to reduce the use cost of batteries and promote the popularization of electric vehicles.
If the waste lithium battery for electric cars is recycled and the elements such as copper, aluminum, nickel, and cobalt in the electrical batteries are recycled by metallurgical technology, which can not only prevent the potential threat of waste battery to the environment but also effectively control the battery cost. Taking the nickel hydrogen power lithium-ion battery as an example, the content of nickel, cobalt, and rare earth in the waste nickel hydrogen power li ion battery is 30% ~ 50%, 2% ~ 5%, and 5% ~ 10%, which has high recovery economic value.
At present, electric vehicles are in the stage of market promotion and have not been widely used. Lithium battery for electric cars have not yet been scrapped on a large scale, so most countries have not yet established a complete vehicle power lithium-ion battery recycling system.
However, some fast-growing cities have made experimental explorations and have established a system for the utilization and recycling of lithium battery for electric cars. For each car sold, the manufacturer will give 600 yuan and the government will give 300 yuan to recycle power li ion batteries, and a battery recycling mechanism will be initially established.
