Graphene Based Supercapacitors are Getting Upgraded
Researchers at the Indian Institute of Technology, Kharagpur, have developed a new Graphene, silver and pyyrole nanocomposite material suitable for making supercapacitors.
The nanomaterial was made of a Graphene sheet onto which silver nanoparticles, each about 15-20 nanometers wide, had been embedded uniformly. The material was shown to have a high specific capacitance of 472 farad per gram at a current density of 0.5 amperes per gram. It could retain 95% of its capacitance after 1,000 consecutive charge-discharge cycles.
Researchers from The University of Manchester recently demonstrated flexible Graphene-based supercapacitors printed directly on to textiles using a simple screen-printing technique.
