I have read with great interest about the use of Graphene to enhance battery technology. Graphene sulfur batteries seem to be a possible better alternative to Lithium ion battery technology. Some researchers claim the increase in efficiency and charge rates could allow a 500 mile battery development. I saw somewhere that perhaps Tesla is working in this direction, perhaps with the planned Gigafactory production. Anyone have any info to share? I found the material to be quite interesting.... if viable, it could catapult the electric car into the forefront and spell the death note for the ICE. What do you all think?
