China Steps Up Battery Recycling Amid Decommissioning Explosion
BEIJING, Dec. 15 (Xinhua) – China is seeking to boost the battery recycling industry to cope with the increasing decommissioning of aging New Energy Vehicle (NEV) batteries, which have grown in popularity in recent years.
China’s Ministry of Industry and Information Technology (MIIT) has announced that it will issue new regulations to clarify the oversight responsibilities of state and local departments, as well as battery recycling requirements, according to Science and Technology Daily.
The latest data from the China Association of Automobile Manufacturers showed that the cumulative sales volume of NEV in China in the first 11 months of this year is around 3 million, accounting for 12.7% of the total vehicle sales volume in China. China.
The lifespan of lithium batteries, which make up the majority of NEVs, is five to eight years, while the effective lifespan is four to six years. Along with the growth in sales of NEV over the years has been an increase in the number of batteries requiring recycling.
In 2020, around 200,000 tonnes of batteries will be decommissioned in China, and by 2025, that figure will be 780,000 tonnes, according to the China Automotive Technology Research Center.
Proper recycling of batteries on such a large scale will greatly reduce the negative impact on the environment, while saving a lot of resources. This can be accomplished by mining the remaining metals and using the echelon, which involves a process of inspection, classification, disassembly, battery repair or reorganization into echelon products which can then be applied to d ‘other areas.
After decommissioning a new energy vehicle battery, there is typically 70-80% capacity remaining, which can be used in scenarios such as energy storage and back-up power to maximize l use of remaining energy.
Batteries that do not undergo staged use can be disassembled and crushed for the extraction of the remaining precious metals, such as nickel, cobalt and lithium, which can be reused for the production of new batteries.
Recent technological advancements have made metal mining safer and more environmentally friendly. For example, waste utilization and pollution control technology for lithium batteries can reduce wastewater emissions by more than 40%.
This technology, invented by the Institute of Process Engineering, affiliated with the Chinese Academy of Sciences, enables the selective recovery of lithium and the treatment of wastewater containing heavy metals, ammonia and nitrogen, thus contributing the proper use of lithium batteries.
In 2020, the process won the first prize of an environmental protection award from the Ministry of Ecology and Environment (MEE). A pilot project using this technology was built to demonstrate how to recycle lithium batteries in an environmentally friendly way.
According to the Institute of Process Engineering, the production and recycling of lithium batteries creates precious metals as well as toxic substances such as solvents and organic compounds. Scientists are working to design safe, efficient and environmentally friendly ways to recycle these materials.
A regulation jointly released by MIIT, MEE, Ministry of Science and Technology and other ministries in August encourages closer cooperation and information sharing among rung user companies, manufacturers of NEV, battery manufacturers and automotive waste recycling companies.
The regulation also encourages battery manufacturers to participate in the phased use of decommissioned batteries.
By the end of October this year, some 171 companies had set up more than 10,000 battery recycling service points across China.
