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).
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.
Modern battery technology offers a number of advantages over earlier models, including increased specific energy and energy density (more energy stored per unit of volume or weight), increased lifetime, and improved safety .
Given the core and innovation of new energy vehicle battery technology, patent application, and authorization have become an important driving force to promote technological progress and industrial development.
Based on this, China's new energy vehicle power battery patent cooperation can be divided into three stages: Stage 1: 2008–2011. The number of collaborative patent applications for new energy vehicle power batteries increased from 4 in 2008 to 72 in 2011, indicating a consistent trend of growth.
