Abstract

The electrical behavior of a material pertains to the conduction behavior (related to the electrical conductivity, which dictates the electrical resistance) and the dielectric behavior (related to the electric permittivity, which dictates the capacitance). Concerning electrically conductive materials, much attention has been given to the former, but little attention has been given to the latter, though both are relevant to applications, which pertain to electrochemical devices (batteries, supercapacitors, etc.) and structural self-sensing (a structural material sensing itself without sensors). The conductive materials studied include carbons (important for electrochemical electrodes), metals, and composites.
