Abstract This study investigated the intellectual property concerns related to recycling spent lithium-ion batteries in China. This report summarizes the technical development trends, main regional distribution networks, critical technical fields, core technical points, and the core applicants. The results show that in the past 3 years, the number of patents related to lithium-ion battery recycling has increased rapidly to over 200 patents/a. There are many cross-disciplinary patents with many patents focused on the electrical components, metallurgy, chemistry, and environmental effects. The main applicants are not just limited to universities and research institutes, but also include a large number of companies since this research has significant industrial value. The stronger national environmental requirements and the increasing demand for resources is leading to many improvements in recycling methods as indicated by the increasing number of patents. Industrial policies, especially pollution prevention and control standards, provide important incentives for further research and for the development of improved recycling methods.
