Abstract: This paper analyzes electric vehicle battery innovation trends using a knowledge-persistence-based main path approach in patent analysis. It identifies three key sub-technological domains: electrodes, energy storage devices and battery charging systems, highlighting dominant and emerging technologies like porous structures and organosulfide electrodes. The USA, Japan and Canada contribute significantly, with leading enterprises including the Province of British Columbia, Fuji Photo Film and Moli Energy. The study provides insights into technological trajectories, offering strategic guidance for future research by identifying high-priority R&D areas like silicon-based electrodes and Internet of Things-integrated charging to inform corporate strategies and policy-making.
