Graphene has the promise to dramatically alter almost every aspect of our lives, but producing it efficiently and inexpensively has proven a major stumbling block to its broader adoption. A state-run South Korean research institute recently announced it has developed a method capable of producing 60 grams of graphene, or a bit over 2 ounces, per hour.
Korea Research Institute of Chemical Technology (KRICT) hopes its development will pave the way for industrial graphene to be mass produced without treating the material with strong acid. The team’s electrochemical stripping process “can send electricity to graphite electrodes to peel graphene into very thin layers,” Graphene-info writes. The resulting peeled graphene is then filtered to extract a powdered form of high-quality graphene.
KRICT has already sent the technology to a company that plans to use the domestically produced graphene in an effort to reduce the nation’s dependence on Chinese imports. The graphene mined natively in South Korea will eventually be used for improved heat resistance in electronic devices like displays and smartphones, as well as secondary battery electrodes.
