Abstract: An increased attention has been paid on supercapacitors around the world due to some desirable properties for energy storage. We investigated the development trend of the technology, research hotspots, research and development directions and competition patterns by using analysis tools including the Thomson Data Analyzer(TDA), the Patsnap and the Derwent Innovations Index (DⅡ) of ISI WoK.The results show that the number of patent applications for supercapacitor technologies has experienced a rapid increase from 2009; the main research and development directions have been focused on electrode materials and electrolytes; and the research hotspots have been mainly on double-layer capacitors, capacitor electrodes, and electrolytes, etc. Top three countries for patent applications are China, Japan and the United States, and top three organizations for patent applications are PANASONIC CORP, NIPPON CHEMICON CORP, and MEIDENSHA CORP.

Key words: supercapacitor, patent technology, research hotspots
