Abstract Scope Ultra-high conductivity metal composites (UCM) developed in the last decade are a highly sought-after technology owing to their application as energy-efficient conductors. Next-generation conductors made with such composites can be used in automobiles, airplanes, and UAVs for light-weighting; in motors and electronics for volumetric savings; and in power grid for energy efficient generation and transmission. In this talk, recent advances in the development of UCMs with nano-carbon additives such as graphene and carbon nanotubes will be presented. Advantages of using melt-free solid phase processing approaches for synthesizing such composites over traditional approaches will be discussed. Material features resulting in ultra-high conductivity will be elaborated. Microstructure, material interfaces, and electron transport pathways conducive for improved electrical performance will be discussed. Effects of carbon additive structure, concentration, and defect density on composite properties will be examined. Finally, current barriers to commercial applications of UCMs and their mitigation strategies will be presented.
