Structural Composite Supercapacitor using Carbon Nanotube Mat Electrodes with Interspersed Metallic Iron Nanoparticles: Additional Data

This additional data for the article, “Structural Composite Supercapacitor using Carbon Nanotube Mat Electrodes with Interspersed Metallic Iron Nanoparticles” [1] presents supplementary methods, microscopy, spectroscopy, electrochemical and structural data for the use of a carbon nanotube (CNT) mat interspersed with metallic iron nanoparticles as a structural supercapacitor electrode material that could be incorporated into fiber-reinforced composites. Advanced transmission electron microscopy and is presented as a full tilt series and then processed using electron tomography and presented as selected slices and models. Composite structural supercapacitor manufacturing method is detailed, and initial results presented.
