A shortage of graphite electrodes for usage in electric arc and ladle furnaces will continue to affect steel mills, sources told S&P Global Platts. In recent years electrode makers have reduced capacity, with some shuttered for good as their mill customers bought competitively priced semi-finished products and re-rolled rather than melting scrap. One supplier, who … Continuar leyendo »

Graphite is a crystalline solid with a black/grey color and a metallic sheen. Due to its electronic structure, it is highly conductive and can reach 25,000 S/cm 2 in the plane of a single-crystal. Graphite is commonly used as the active material in negative electrodes mainly because it can reversibly place Lithium-ions between its many layers.

Northern Graphite’s main asset is the Bissett Creek graphite project in Ontario. The estimated capital cost for the project is C$110 million, with the company hoping to be in production in 2022.

Previous studies have suggested that members of the Geobacteraceae can use electrodes as electron acceptors for anaerobic respiration. In order to better understand this electron transfer process for energy production, Geobacter sulfurreducens was inoculated into chambers in which a graphite electrode served as the sole electron acceptor and acetate or hydrogen was the electron donor.
