How to establish a recycling and maintenance mechanism for power lithium batteries?

How to establish a recycling and maintenance mechanism for power lithium batteries With the vigorous development of the new energy automobile industry, the recycling and utilization of power lithium batteries has become the focus of attention in the industry. After recent years of development, the time for new energy vehicles to be wasted in batches will come. If a large number of discarded batteries cannot be properly recycled, it will not only lead to waste of resources, but also environmental pollution and other problems. With the establishment of the production responsibility extension system with automobile companies as the main body, the power lithium battery recycling industry has entered a critical period of channel construction. The Ministry of Energy Conservation and Comprehensive Utilization, the former deputy inspector, and the Secretary-General of the my country Electronics Energy Conservation Technology Association held the April 17th Automotive Power Lithium Battery Recycling and Secondary Battery Recycling and Regeneration Technology Seminar. The design of the power lithium battery production is in my country and waste power lithium battery recycling, disposal and comprehensive utilization should now support standardization in the initial stage of development. Industry pain points: high cost and weak economy. The retirement life of new energy passenger vehicles is generally 5 years, and the retirement life of passenger cars and commercial vehicles is generally 3 years. Before 2022, retired batteries will be dominated by lithium iron phosphate batteries. After 2022, the number of retired three-pole batteries will be equal to that of lithium iron phosphate batteries, and will gradually surpass that of lithium iron phosphate batteries. In 2018, the theoretical scrap volume of power lithium batteries is expected to be 5.14GWh, mainly from new energy buses. The reporter learned that the current layout of related companies is mainly divided into five categories: traditional recycling companies, emerging recycling companies, battery factories, battery materials companies and whole plants. Different types of companies have different advantages and disadvantages. For example, traditional recycling companies have comparative advantages in recycling channels, material recycling technology, battery crushing technology, and smelting technology. However, due to the lack of sources of power lithium batteries, they still have to cooperate with car manufacturers and scrap factories. The advantages of emerging recycling companies are mainly reflected in battery crushing and dismantling technology. At present, the treatment methods of waste batteries mainly include fire smelting technology and wet smelting technology. Wang Haibei, Dean of Metallurgical Design and Research Institute of Beijing Mining and Metallurgical Technology Group Co., Ltd. The smooth operation of the recovery system must be based on profitability. If there is no profit drive, the company's enthusiasm cannot be fully enhanced. Existing recycling technology and recycling network construction investment is very large, although many companies have set up to test the water, but few companies dig big buckets of gold. It cannot be ignored that toxic electrolytes and harmful gases will appear in the battery recycling process. If handled improperly, it will bring great harm to the environment and human health. Some companies use high-temperature heating or combustion in the production process, and improper control can easily endanger the health of workers. Ming Yuebin, general manager of Harbin Baterui Resources Recycling Technology Co., Ltd. pointed out. The government and the company work together to find solutions. In response to the above problems, relevant government departments have issued a series of industrial policies to guide and regulate the power lithium battery recycling industry. In February of this year, seven ministries and commissions including the Ministry of Industry and Information Technology jointly announced the 'Interim Measures for the Management of Recycling and Utilization of Power Lithium Batteries for New Energy VehiclesIn March of this year, the Ministry of Industry and Information Technology (Ministry of Industry and Information Technology) and other seven ministries jointly announced a notice on the recycling organization of the pilot project of new energy vehicle power lithium batteries. It is recommended to carry out pilot projects in the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta. And the central region. The announcement of the above notice marks the gradual establishment of my country's recycling policy system. Yang Qingyu said: With continuous breakthroughs in related technologies, the speed of policy announcements will accelerate, and relevant standards are expected to be announced this year.
