Patent Analysis on Graphene Materials in Lithium-Ion Batteries

Abstract:

Graphene is one of the most promising new electrochemical materials for lithium-ion batteries (LIBs) because of its superior electronic properties. In this work, we describe the patent map on graphene-based LIBs. We discuss the time-line for the amount of patent applications on LIBs, the nation and applicant distribution of the patent applications. We analysis the technology distribution in this field, which shows that applications about graphene-based cathode increase really fast. According to the analyse result, the Chinese patents have occupied the leading position in this new field but the applications are mostly submitted by colleges and research institutes, which suggests that few inventions have been implemented. In order to hold the market trends and improve competitiveness, it is necessary to keep eyes on worldwide patent application situations and build effective patent strategy, therefore, we also raise some advices and countermeasures about the graphene-based LIBs.
