石墨烯在储能领域应用的专利分析

Patenting activity of graphene for energy storage

为研究石墨烯在储能领域研究开发的知识产权现状,以锂离子电池、超级电容器、锂硫电池、锂空气电池、锂金属电池、钠离子电池、铅炭电池等电化学储能体系为切入点,对石墨烯在储能领域应用技术进行专利检索,并从全球专利申请趋势、主要来源国家、各结构部件中应用专利分布、重要专利申请人等方面进行了详尽的分析。以期为我国石墨烯储能技术创新及产业发展规划等提供有价值的参考。

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.
