With the popularization and promotion of electric vehicles, even though electric vehicles claim zero emissions, the environmental pollution of waste batteries during the recycling process is still deadly. The problem of waste battery recycling and reuse has become a topic of concern for many users. The industry pointed out: "Clean and environmental protection is the trend of motor vehicles in the future."

Recycling of batteries is imminent At present, research on domestic power batteries is mainly focused on improving performance, and the attention on recycling is obviously insufficient. At this stage, lithium-ion batteries are widely used in electric vehicles. They do not contain heavy metals such as mercury, cadmium, and lead, which are harmful to the environment. However, materials such as positive and negative electrodes and electrolyte solutions are very harmful to the environment. Great influence.

Waste batteries still have utility value The actual use time of general electric vehicle batteries is about 3 to 8 years. However, these used batteries still have utility value. “For energy storage systems, establishing a power battery cascade utilization and recovery management system may be a viable option.” Chen Quanshi, professor at Tsinghua University, said, “Batteries with less than 80% capacity can continue to be used for energy storage in the grid, or as The power source of low-speed vehicles such as electric field vehicles also has secondary use value.” The use of ladders allows the value of power batteries to be fully utilized, thereby reducing the cost of battery use and promoting the popularization of electric vehicles.

The recovery system needs to be improved At present, electric vehicles are in the stage of market promotion, and there is no large-scale application. Electric vehicle power batteries have not yet appeared in large-scale scrap situation. China has not yet established a complete vehicle power battery recycling system. According to the author's understanding: Shenzhen Energy Saving and Energy Vehicle Demonstration and Promotion Leading Group stated that Shenzhen has established a vehicle battery power utilization and recycling system. "Every car manufacturer sells 600 yuan, and the government pays 300 yuan for the recovery of power batteries, initially establishing a battery recycling mechanism."
