Abstract: In this paper, we studied the distribution patents and the technology development of supercapacitors. The patent information in this paper is collected from the patent database of Derwent Innovations Index (DII). We analyzed the publication year, countries, subjects, key applicants by using of TDA and innography. Based on the analysis, we got the present international situation and trend of supercapacitor energy storage technology.

Key words: supercapacitor, energy storage, patents analysis
