Improve the power battery recycling system to solve the root cause of battery pollution

With the development of my country's new energy automobile industry, the power lithium battery itself is gradually focusing on environmental pollution, and the recycling of power batteries is still a big problem. It is urgent to build a complete and complete power battery recycling system. Due to the improper handling of cathode materials and electrolytes in power batteries causing huge pollution to the environment, and the country has not yet issued specific laws to regulate the recycling of power batteries. At the same time, various car companies and battery manufacturers have not found a complete battery recycling system. Therefore, everyone is very worried about whether power batteries will cause environmental pollution. Today, I will take you to take a look at the successful experiences in the recycling and utilization of power batteries in developed countries that are worth learning from. For the recycling and reuse of power batteries, the currently commonly adopted method is: cascade utilization + regeneration treatment. For the retired power batteries of new energy vehicles, the residual energy is more than 70%. After selection and testing, they can be further used in energy storage, distributed photovoltaic power generation, household electricity, low-speed electric vehicles and other fields; It is further decomposed and regenerated. At present, domestic power battery recycling companies have outstanding problems such as poor professionalism, poor safety, low entry barriers, and irregular dismantling. First, the technical specifications are not perfect and the recycling system has not been established; referring to the previous recycling of lead-acid batteries, it can be seen that many small workshops on the market use unscientific methods to recycle and dismantle lead-acid batteries. The waste electrolyte contains sulfuric acid, Lead sulfate, etc., the use of backward methods to recycle lead batteries will cause waste to enter the environment at will, and the smelting process will produce a large amount of lead-containing smoke or heavy metal wastewater, causing serious environmental pollution, such as the blood lead that has occurred many times in my country in recent years. event'. The second is that the specific recycling requirements of the policies introduced are not clear. The requirements for the recycling of power batteries in the 'Notice on the Financial Support Policy for the Promotion and Application of New Energy Vehicles from 2016 to 2020' and 'New Energy Vehicle Manufacturers and Product Access Management Rules' It's just that'enterprises should bear the main responsibility for power battery recycling','new energy automobile manufacturers should establish a new energy automobile product after-sales service commitment system including battery recycling'; third, there is a lack of incentives and penalties for power battery recycling, and the current policy is not mandatory Management, the enthusiasm of enterprises is not high, it is necessary to formulate incentive rules for power battery recycling, and establish a clear reward and punishment mechanism. Comparing the current status of battery recycling in the above-mentioned countries, it can be seen that in addition to having advanced power battery recycling technologies, these countries also have relatively sound legal and regulatory protections. At present, in order to guide and promote the cascade utilization of power batteries, the national policy level has continuously issued policies, but China still lacks professional laws and regulations, and recycling companies also lack relevant strict management systems. Therefore, it is also necessary for China to learn from relevant foreign experience to establish a complete power battery recycling system.
