Benefitting from exceptional physicochemical properties, graphene-based materials are able to harvest energy from external factors such as moisture and heat. Graphene oxide is formed by the oxidation of graphite which is cheap and readily available.Graphene oxide is dispersible in water and other solvents. Materials engineering is being conducted by the world leading electronic materials team at UNSW. Early stage work with graphene oxide ink at UNSW includes:Fabrication of over 100 battery cells by coating the graphene oxide ink onto glass.Self-charging time using water vapour in the air of approximately 3 mins.Extremely thin battery cells at around 10-20 microns. Thinner than a human hair.Small size of 1 cm with potential to be made much smaller.Generation of more than 0.7 Voltsof power a cell. 3.7 Volts goal from connected cells in 12 weeks.
