A team of researchers in the US (University of Central Florida, NASA Kennedy space Center, FL) has developed a supercapacitor using carbon fiber reinforced polymer (e-CFRP) that can store electrical energy and function as the structural component for the EV’s body shell.
Vertically aligned graphene sheets were attached to carbon fiber electrodes on which different metal oxides were deposited to obtain high-energy density electrodes. They fabricated a high-strength multilayer e-CFRP assembly using an alternate layer patterning configuration of epoxy and polyacrylamide gel electrolyte. It delivered a high areal energy density of 0.31 mWh cm–2 at 0.3 mm thickness and a high tensile strength of 518 MPa, bending strength of 477 MPa, and impact strength of 2666 J m–1. It was demonstrated by applying it to a toy car’s body panel…read more. TECHNICAL ARTICLE
