KRICT team develops improved graphene production method

wallpapers News 2020-12-23

A state-run research body in South Korea opened the way for the mass-production of high-quality industrial graphene in powder form without treating graphite with a strong acid. A domestic company will seek commercial production within this year.

The Korea Research Institute of Chemical Technology (KRICT) said its research team has developed an electrochemical stripping process that can send electricity to graphite electrodes to peel graphene into very thin layers. The peeled graphene is extracted in powder form through a filter. The process can reportedly produce 60 grams of high-quality graphene per hour.

The resulting material was said to be superior in all aspects, including price and quality, to graphene produced by chemical synthesis process - a way to obtain graphene by treating graphite as a strong acid.

KRICT has transferred its technology to a company that will use graphite produced in a domestic mine to reduce South Korea's dependence on Chinese imports. Graphene produced in South Korea will be used as heat-resistant parts for electronics such as displays and smartphones, and secondary battery electrodes.
