Asphalt, Graphene, and a Lithium Coating Mike Williams, reporting for Rice University in Houston, Texas, writes, “A touch of asphalt may be the secret to high-capacity lithium metal batteries that charge 10 to 20 times faster than commercial lithium-ion batteries, according to Rice University scientists.” We’ve written about James Tour and his laboratory before.  He and his students come up with a plethora of new energy ideas and are able to demonstrate some exciting outcomes.  His latest effort mixes asphalt with conductive graphene nanoribbons, and then electrochemically coats the composite with lithium metal to form a battery anode. The anode, when combined with a sulfurized-carbon cathode, was used in full batteries for testing.  The results seem a bit incredible, with …
