Developing advanced recycling technologies for spent lithium batteries and building a domestic self-sustaining circular industry ecosystem （Year 2）
| 英文摘要 | Through recycling technologies, valuable resources can be extracted from retired lithium batteries, reducing production costs and enhancing the economic efficiency of the green energy industry. This project developed low-carbon, high-value recycling technologies for waste lithium iron phosphate batteries, integrating carbon coating and lithium replenishment processes to significantly improve the performance of regenerated materials. The technology effectively separates active materials and impurities, reduces aluminum impurities to below 400 ppm, addresses increased internal resistance, and achieves a specific capacity exceeding 99% of new materials. Testing demonstrated that regenerated materials mixed with new materials meet the EU Battery Regulation requirements, reduce carbon emissions by 64.1%, and improve recycling cost efficiency by 57.4%. During the project, a material flow chart of the domestic lithium battery industry was completed, along with guidance for three industrial supply chains. International carbon footprint calculation methods were introduced, revealing that the estimated carbon reduction benefit from the recycling of waste lithium batteries in 112th yearis 427.04 metric tons of CO2 equivalent (t CO2e). The main carbon emission hotspot is the incineration of waste plastics, which accounts for 65.6% of the total carbon emissions. It is estimated that the carbon reduction benefit from waste lithium battery resource recycling in 114th year will be 523.66 metric tons of CO2 equivalent (t CO2e). To align with international policies, the project analyzed the EU Battery Regulation and related measures, including targets for recycling efficiency and carbon footprint declaration formats, and compiled the findings into a report for domestic strategy reference. Additionally, a lithium battery identification and sorting module was developed, integrating AI training models and optical recognition systems. The database now contains over 3,303 feature data points, achieving a sorting accuracy of over 83%, effectively reducing impurities in regenerated materials. | ||
