Ministry of Industry and Information Technology, Ministry of Science and Technology, Ministry of Environment, Ministry of Transport, Ministry of Commerce, AQSIQ Research on scientific and technological research of dynamic battery recycling, guiding production and research collaboration, encouraging ladder utilization and regeneration utilization, driving power storage battery recycling mode innovation. Implement the production of the owner's responsibility extension system, the automobile production company undertakes the main responsibility of the power storage battery recovery, the relevant company performs corresponding responsibility in the power storage battery recycling, guarantees the effective utilization of the power battery and environmental disposal. Adhere to the product full lifecycle concept, follow the principles of environmental benefits, social and economic benefits, and give full play to market use.

Zhen lithium research believes that clarity of the main responsibility of the automotive production company to take the power storage battery, will greatly promote the development of the powerful lithium battery recovery industry, and can promote the innovation of car companies in business model, and protect the effective use of power storage and environmental protection Disposal, build a closed-loop management system. It is expected that there will be more and more car companies in the future to join the row of power lithium batteries. According to ZHIHV research data, my country Electric Automobile Market realized a total of 33.

55GWH in China's electric vehicle market, up 21% year-on-year, and by 2020, the installed volume will reach 104.41GWH. According to ZHIHHLV research data, 2017 new energy vehicle dynamic lithium battery retransmission rate reached 36,000 tons, up 140% year-on-year, 2018-2020 will reach 118,000 tons, 141,000 tons, 196,000 tons.

At present, the dynamic lithium battery recycling is important renewable cycle utilization and ladder utilization model, and the regeneration cycle is very similar to the process of domestic and foreign. First, discharge, then disassemble the battery to disassemble the positive electrode, negative, electrolyte and Component part of the diaphragm. Then the electrode material is leached, the acid is immersed, and the extraction is performed to achieve the enrichment of the viable metal.

There are two important methods for renewable recycling. , Especially the emergence of exhaust gas, and the random discharge of waste, waste acid, waste base, and become an important cause of secondary environmental pollution. The ladder utilization of the power lithium battery is also facing a large problem, the biggest problem is cost.

Taking a 3MW * 3H energy storage system as an example, after considering factors such as investment costs, operating costs, charging costs, financial expenses, such as the power lithium battery used by the ladder as the battery battery, the system's full life cycle cost 1.29 yuan / kWH, and the newly produced lithium-ion battery as a battery of the energy storage system, the system's full life cycle cost is 0.71 yuan / kWh, which shows that the ladder utilization power lithium battery is significantly higher than the new battery.

Its important reason is that the stage of the ladder is not yet mature, resulting in the dismantling of the retired dynamic lithium battery, the detection, selection, and recombination of the available modules, etc. At the same time, due to the poor consistency of the ladder, a part of the cost is added to the purchase of strengthening system stability when purchasing related equipment. These costs are important factors that restrict the development of ladder dynamic lithium batteries in the promotion of energy storage industry.

At present, although the concept of the tradder is accepted, how to perform and combine with the recycling cycle, establish a complete system or blank. At the same time, there is also a sustainable development study of the related lithium-ion battery regeneration industry and circular economy models. Zhen lithium research analysts believe that in the process of future dynamic lithium battery recovery, by establishing an efficient and reliable lithium-ion-powered lithium battery ladder, and further strengthening the research and development of related technologies, achieving unobstructed environmentally friendly materials Decompose the recovery requirements, so that the secondary pollution and recovery costs of the environment can be gradually subtracted, and in terms of power lithium battery companies, through the improvement of the dynamic lithium battery product structure design and production process, it can also reduce post-recovery.
