Graphene is one of carbon’s allotropes and a key-element related to diamond, glassy carbon, carbon nanotubes and others. Currently used in photovoltaic cells, transistors, gas sensors, computers and batteries as well as having many useful applications in other fields, – graphene is expected to revolutionize the existing supercapacitors – as reported by researchers from University of California, Los Angeles, USA. They announced their efforts to develop completely flexible and robust electrical double layer capacitors, using a laser-writing technique, similar to DVD-burning process. Learn more about graphene, its properties and potential usages – in this book.
