Researchers have found a way to successfully synthesise three-dimensional graphene in mass production quantities, opening the door to its eventual use in high performance electric vehicles.

Technology (UNIST) has developed an environmentally-friendly, high-yield process for synthesising highly conductive 3D mesoporous graphene: a material riddled with tiny holes to increase its surface area.

Offering better conductivity than standard graphene, the three dimensional material could be used to make more efficient electrodes for supercapacitor applications. For example, the long life and power-handling characteristics of supercapacitors make them a preferred power source for future high performance electric vehicles.

Current high-quality commercial graphene manufacture couples low yields with potentially large environmental impacts such as the release of toxic gases. By contrast, 3D mesoporous graphene offers higher-volume and cleaner mass production.
