New energy power battery technology is a highly patent-intensive field, and patent protection and cooperation are crucial to the development and application of the technology. Patents are the result of technological innovation and an important indicator of technological innovation behavior (Archibugi 1992).
The analysis process primarily targets resource and environmental issues in the production stage of power batteries.
Against the background of patent proliferation and open competition, the power battery industry is facing multiple innovation breakthroughs such as the research and application of new battery materials, high-efficiency electrode design multi-power supply integration, etc.
Future research can strengthen the research on international cooperation networks, including the analysis of international patent cooperation mode, characteristics, and trends, to provide broader development space and cooperation opportunities for China's new energy vehicle power battery industry. Data will be made available on request.
Subsequently, a thorough analysis is conducted to examine the spatial patterns of patent cooperation within each province specifically about new energy power batteries. Figure 4 shows that the total number of provinces involved in new energy power battery patent cooperation is increasing throughout the three stages.
Phased evolution of the patent cooperation network: From 2008 to 2021, the evolution of the new energy vehicle power battery patent cooperation network presents significant phased characteristics, which not only reflect the rapid development of technology but also reflect the deepening of the industry-university-research cooperation mode.
