The best lithium air lab research batteries had cathodes built with graphene nanosheet materials.  Back in August of 2011 scientists at the Nanomaterials and Energy Group at the University of Western Ontario (UWO), Canada, reported the development of graphene nanosheet cathode (GNS) materials for non-aqueous lithium-oxygen (Li-air) batteries showing a capacity of 8,705.9 mAh g-1 […]
