Supercapacitors are considered one of the newest innovations in the field of electrical energy storage. For example, charging is completed within a few seconds and the laptop keeps running for at least a month, etc. Innovative high-power supercapacitors are the latest research achievement funded by the EU's seventh research framework program (FP7), led by Professor Jari Kinaret of the Swedish Chalmers University of Technology and developed by the collaborative research and development team of AUTOSUPERCAP in Europe. Innovative high-power supercapacitors are usually used for charge storage, and most recently used with graphene material technology to store more energy, last longer time with a smaller volume and weight compared to traditional rechargeable battery. This solved three issues with the sustainable development of renewable and efficient use of energy: 1) To efficiently reduce the cost of energy storage; 2) to solve the embarrassing situation for electric vehicle to stop for charging a few hours every hundreds of kilometers travelling; 3) Most importantly, it makes up for the main flaw of wind power or solar power depending on wind or sunshine to store more energy.
Constitution of unit capacitors with thin layers of high strength carbon atoms and highly conductive graphene film materials are involved in the fine carbon nanotubes and arranged to constitute base modules and further to supercapacitors. “High-power supercapacitor manufacturing process is relatively complex so that further effort for the engineers and technicians to find out the economic reasonable scaled manufacturing process is needed.” said Prof. Andre Geim, the winner of 2010 Nobel Prize. In addition to the above reason, the wide application prospects of graphene materials in advanced manufacturing, power electronics, medical devices and super miniature plastic industries, promote Future Emerging Technologies (FET) Graphene Flagship Project officially launched by the European Commission and aimed at accelerating the process of commercialization of graphene applications.
