Abstract:

This study takes electrochemical energy storage systems (e.g., lithium-ion batteries, supercapacitors, lithium-sulfur batteries, lithium-air batteries, lithium-metal batteries, sodium-ion batteries, and lead carbon batteries) as the starting point to conduct a patent search on graphene applications and understand the current status of the patenting activity of graphene applications in the energy storage field. This paper also presents a detailed analysis of the global patent application trends, main source countries, applied patent distribution in various structural components, and important patent applicants. The results of this study are expected to provide a valuable reference for China's graphene energy storage technology innovation and industrial development planning.

Key words: patent, graphene, energy storage, lithium batteries, supercapacitors
