Technique developed to produce graphene from discarded dry cell batteries
A group of researchers at Nagpur-based Visvesvaraya National Institute of Technology have developed a new technique which promises to help produce high value graphene from discarded dry cells batteries.
Graphene, a form of carbon, is transparent and flexible conductor with a range of applications including in making solar cells, light-emitting diodes, touch panels and smart windows. Graphene supercapacitors serve as energy storage devices with a capacity for faster charging and longer life span than traditional electrolytic batteries. Graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice. It is the strongest material to be ever tested, conducts heat and electricity efficiently.
Since graphene is made out of graphite, its production is both expe...
