graphene

Korean researchers have developed a technique to make the first reusable fuel cell electrode material.

By selectively coating the metalloid antimony with graphene in a mechanochemical process, the scientists at the Ulsan National Institute for Science and Technology managed to maximise the electrode’s electrochemical activities.

Due to the costs of platinum, commonly used in fuel cells, graphene has long been talked about as a replacement. But until now the electrochemical activities in the material has been too low.

The development process of the electrode has been transferred to a Korean company and is expected to be commercialised, reports Business Korea.

The findings of the study were first published in the scientific journal Nature Communications’ May issue.

Canada’s graphene products developer Grafoid has bought lithium-ion automotive battery maker Braille Battery.

Grafoid acquired 75% ownership interest in US-based Braille Battery, which produces lightweight lithium-ion batteries and AGM lead-acid batteries for IndyCar, NASCAR, Formula 1 racing cars, motorcycles and batteries for the marine industry. Braille Battery’s founder Blake Fuller will remain president and chief operating officer.
