NETL supports an innovative technology that transforms carbon-rich materials including coal and coal-wastes into high quality graphene for use in a wide range of products is closer to reality. The progress can have positive implications for a wide array of materials that are a part of everyday life.
Universal Matter, an international research and development company, received support from NETL’s Carbon Ore Processing Program through a cooperative agreement. The company has demonstrated a graphene production technology called Flash Joule Heating (FJH), which can transform carbonaceous material feedstocks, including coal and coal-wastes, to high quality graphene.
Producing Large Scale Graphene at Low Cost
According to Universal Matter, graphene is a versatile carbon-based nanomaterial that is 200 times stronger than steel and can stretch up to 25% of its original length. Graphene consists of tightly bonded carbon atoms arranged in a hexagonal lattice. It is more electrically conductive than copper, possesses extremely high thermal conductivity and is stronger (tensile strength) than any known material.
Joe Stoffa, NETL’s technology manager for the Carbon Ore Processing Program, said that producing high-quality graphene on a large scale at a low cost could enable several disruptive technologies.
“
Universal Matter’s FJH process can convert diverse carbon sources into graphene with tunable characteristics for an almost unlimited number of applications. Universal Matter’s scale-up of FJH graphene production is key because it means the nation’s carbon ore resources can have a significant additional application beyond their traditional use in power generation and metallurgy,” said Stoffa.
According to the Graphene Council, aerospace engineers are looking at graphene and other advanced materials as key enabling technologies for the next generation of aircraft and space vehicles. In the automotive industry, graphene could play a major role in the future of transportation due to its broad range of performance attributes.
For example, graphene can improve lithium-ion battery charging speed and capacity, can be added to polymers to decrease automobile weight and can be incorporated into carbon-metal composites to make smaller and less expensive electric motors and inverters.
Additional applications for graphene include composites, asphalt, anti-corrosion coatings, concrete and cement, electronics, lubricants, plastics, polymers, rubber and synthetics, semiconductors, sensors, structural materials, textiles, thermal management and water filtration.
