Lithium-ion batteries, as one of the three core components of electric vehicles (battery, motor, and control), play a crucial role in determining the range and power performance of EVs. Although the cost of power batteries has decreased in recent years with technological advancements, data indicates that they still account for approximately 30% to 40% of the total cost of electric vehicles. For EV owners, regular maintenance of the power battery is particularly important.
Insufficient awareness exists among the public about the pollution from the undercarriages of new energy vehicle lithium batteries. There is yet no self-consciousness in collecting the discarded undercarriages of new energy vehicles. Although the recycling of used new energy vehicle lithium battery undercarriages has gained attention from relevant departments in recent years, the results have been minimal. There is a need for vigorous promotion of recycling awareness and to enhance public understanding of the significance of recycling and utilizing discarded new energy vehicle lithium battery undercarriages.
Properly recycled for new energy vehicles' lithium battery undercarriages can transform into excellent "urban mines," as the metal resource abundance within the batteries far exceeds that of mineral reserves. The raw materials obtained from recycling these batteries can then be utilized by battery manufacturers and their upstream and downstream companies in the supply chain, achieving resource conservation. Moreover, the promotion of the battery swapping model will benefit car manufacturers or power battery manufacturers as the main recyclers by securing the source of used batteries in advance, enabling bulk recycling and thus enhancing recycling efficiency.
New energy vehicle lithium battery undercarriages contain valuable resources such as cobalt, lithium, copper, and plastic, all of which have high recyclability. Therefore, scientifically and effectively disposing of new energy vehicle lithium battery undercarriages not only yields significant environmental benefits but also offers good economic returns. To alleviate the increasingly severe resource shortages and environmental pollution caused by economic development, achieve full-component recycling and utilization of spent lithium-ion batteries.
New energy vehicle lithium battery packs typically contain 5%~15% cobalt, 2%~7% lithium, and 0.5%~2% nickel, with their recycling and reuse potential relatively high; lithium-ion batteries also contain toxic substances like lithium hexafluorophosphate, which can severely pollute the environment and ecosystems. Heavy metals like cobalt, manganese, and copper can also harm humans through bioaccumulation in the food chain, posing a high risk. As the application of lithium-ion batteries becomes more widespread, recycling valuable metals from new energy vehicle battery packs, reducing environmental pollution, and alleviating resource scarcity issues carry significant social importance.
With the increasing application of lithium battery powertrains in new energy vehicles, recycling the valuable metals from these batteries, reducing environmental pollution, and alleviating resource scarcity hold significant social and economic importance. The spent lithium battery powertrains of new energy vehicles contain a large amount of heavy metals, as well as electrolyte solutions like waste acid and alkali. If disposed of carelessly, the leakage of heavy metals from the spent batteries can pollute water bodies such as rivers, lakes, and seas.
While vigorously developing lithium-ion batteries, it is crucial to pay attention to the research of resource recovery and utilization technology for the bottom plates of waste new energy vehicle lithium batteries. This not only brings economic benefits but also transforms waste into treasure, truly realizing the sustainable development of resources and the environment, and becoming an important link in the new energy industry chain.
New energy vehicle lithium battery underbodies contain a large amount of heavy metals, as well as electrolyte solutions like waste acid and alkali. If disposed of carelessly, the leakage of heavy metals from the scrapped new energy vehicle lithium battery underbodies can pollute water bodies such as rivers, lakes, and seas, indirectly threatening human health. Therefore, recycling and disposing of scrapped new energy vehicle lithium battery underbodies not only addresses the pollution source but also achieves the recycling and reuse of resources.
Disposing of lithium-ion battery trays from new energy vehicles can pollute the environment and harm human health. Recycling these trays is of great significance, as it effectively raises awareness of the importance of recycling waste batteries, fosters a sense of social responsibility for environmental protection, and promotes a positive atmosphere of environmental awareness throughout society.
The raw materials generated from the recycling of new energy vehicle lithium battery undercarriages mainly include anode and cathode materials, electrolytes, electrolyte solvents, separators, binders, etc.; if not recycled effectively and environmentally, these materials can cause certain damage to the environment. For instance, heavy metals like cobalt used as cathode materials can alter the pH balance of the environment, and electrolytes and their solvents may lead to fluorine and other pollutants, which could have corrosive effects on human skin.
New energy vehicle lithium battery undercarriage recycling and processing refers to the centralized collection of scrapped lithium batteries, recycling the batteries through physical, chemical, and other recycling processes, or extracting valuable metals such as lithium, cobalt, and nickel from the batteries.
