The proposal points out that although the state has successively issued a number of policies in building a recycling system for used lithium batteries in recent years, overall, there are still some problems.
first, the technical standards are not high. In terms of key technologies, there are some shortcomings in the front-end of power lithium battery recycling, such as the judgment standard and detection technology of power lithium battery decommissioning, the residual value evaluation technology of cascaded batteries, the automatic disassembly of single batteries and the material sorting technology.
second, the development momentum is insufficient. The policies issued by the relevant state departments on the core measures for recycling power lithium batteries are not binding, and there is a lack of supporting incentive mechanism and supervision means in scientific research project planning, finance and taxation, business environment and so on. At the same time, limited by the recycling cost, technical level and processing scale, most enterprises in the industry are in a state of slight profit or even loss.
thirdly, there is not enough scientific and technological support. The research on scientific research projects related to lithium battery recycling is fragmented, lacking systematicness, and the transformation ability of scientific research results is insufficient. The phenomenon of Industry-University-Research disconnection still exists.
fourth, there are environmental risks. In the treatment process, because China has not formulated the pollutant discharge standards for the waste lithium battery treatment industry, especially the emission limits have not been set scientifically, many enterprises have improperly recycled and disposed of them, resulting in water and heavy metal pollution.
Therefore, the proposal suggests:
Continue to strengthen technical research in the industry. First, continuously improve the research and development of key technologies. It mainly includes the criteria and detection technology of lithium battery decommissioning, the evaluation technology of residual value of cascaded batteries, the automatic disassembly and material sorting technology of single batteries, etc. The second is to continuously improve the existing recycling technology and process level of waste lithium batteries. Encourage enterprises to actively develop recycling technologies that are easier to achieve batch processing and less subsequent pollution, and promote the construction of engineering and technical capabilities throughout the industrial chain. Third, actively use the Internet, big data, Internet of Things and other high-tech technologies to improve the evaluation and sorting efficiency of waste power lithium batteries. Strengthen the application of information technology in the whole life cycle of power lithium batteries, and build a reverse big data system by combining new energy vehicles, power lithium batteries, power lithium battery sorting and dismantling companies, and realize traceability management.
Establish an effective incentive mechanism and restraint mechanism. First, the national key research and development plan projects should focus on supporting the research and development of key technologies and key equipment for recycling lithium batteries, as well as the research and development of new technologies and processes for recycling lithium batteries. The second is to set up an incentive fund, explore the establishment of a deposit system for the recycling of power lithium batteries, and give peer-to-peer incentives to consumers of new energy vehicles and automobile scrapping and dismantling companies. The third is to give tax incentives to lithium battery recycling companies and subsidize low residual power lithium battery recycling companies. The fourth is to establish a recycling market and a public service platform for waste lithium batteries, and improve the evaluation mechanism and pricing mechanism for waste power lithium batteries.
explore the establishment of an intellectual property trading platform within the industry. In view of the fact that the patents of lithium-ion battery recycling technology are scattered and the patentees in other fields lack channels to share benefits, relevant departments should promote the establishment of a special intellectual property trading platform while releasing industry technical standards, and handle related legal issues well to avoid technological monopoly. According to the principles of fairness, rationality and non-discrimination, the patent transfer fee standard is issued, which promotes lithium battery recycling enterprises to follow the standard and reduces the cost and risk of enterprise technology research and development through information docking and property right certification. Broaden the technical contact channels within the industry, encourage the formation of intellectual property aggregates within the industry, and enhance the overall technical level of the industry.
attach great importance to pollution prevention and control through recycling. Accelerate the formulation of technical specifications and industrial pollutant discharge standards, guide recycling enterprises to standardize pollution control processes, facilities and efficiency, reduce the discharge of toxic and harmful substances, and strengthen pollution prevention and control in the process of recycling and disposal. Carry out special investigation of pollutants in power battery production industry and comprehensive utilization industry, find out the production and discharge base of pollutants in the industry, and carry out research around the release routes, migration and transformation laws, environmental exposure levels and environmental effects of key toxic and harmful substances, so as to provide scientific basis for subsequent environmental management decisions.
