cResearchers at the US Department of Energy's Pacific Northwest National Laboratory have made a significant breakthrough in the field of metal conductivity..
Their discovery, published in the journal Materials & Design, uses graphene to improve the temperature coefficient of copper.

This important property explains the heating of conductors during the passage of electric current.. Adding just 18 parts per million of graphene to electrical copper reduced the temperature coefficient of resistance by 11 percent while maintaining electrical conductivity at room temperature.
This discovery contradicts the generally accepted view of metals as conductors, where additives typically increase their heatability under electric current.. However, the researchers were able to increase the electrical conductivity of copper, which could have important implications for the efficiency of electric vehicle motors and energy distribution in businesses and homes.

Scientists have applied for a patent for this discovery, which could lead to more efficient use of electricity and more efficient technologies in the energy industry.
The research team plans further experiments to evaluate other important properties of this new material, including its strength, corrosion and wear resistance, which are critical for its industrial applications.
