Solar power graphite alkenyl electrochemical capacitor energy storage research progress

It is known that the electrochemical capacitor with quick charging, high power, long cycle life, wide working temperature range, high safety, can be used as power supply, in hybrid electric vehicle, standby power supply, portable electronic devices, and other fields have broad prospects for development. On February 17th, nature & ndash; Energy 'online published titled' adjustable layer spacing, solar thermal cycle button hole efficient utilization of graphene films electrochemical capacitor energy storage research papers, the research team from the metal research institute, Chinese Academy of Sciences, the university of Hong Kong, and university college London. For this, the researchers were different proportions of oxidation reduction graphene graphene and thermal expansion of mixture, after vacuum suction filter, get the lamella spacing adjustable composite graphene base film, and through regulating the lamella spacing, photovoltaic stents w achieved the effect of porosity in the optimization of the electrode materials. ” Heating system heat exchanger station, however, electrochemical capacitor compared with its low energy density batteries, heating system heat exchanger station that is the energy stored per unit volume is low, limits its wider application range, especially in the application of portable intelligent devices, solar panels, the need to further improve the volume energy density. Photovoltaic stents w on this basis, the solar energy, solar thermal cycle button researchers designed a flexible solid-state electrochemical capacitor, solar energy, graphene membrane electrode material itself good bending performance, to ensure the flexibility of the entire device, and the further development of the intelligent device, according to the actual demand change circuit connection way, qian xuesen systems thinking to achieve the effect of different output. Papers to corresponding author metal by researcher of Chinese Academy of Sciences, qian xuesen system thinking badad introduced: & other; When the pore size of electrode material and electrolyte ion size matches, China solar energy network, pore space utilization to optimization, China solar power network, thus maximizing the volume energy density.
