Melbourne-based Syrah Resources Ltd. will supply Elon Musk's company with graphite anode material for an initial four years, with an option to buy additional volumes subject to further expansion at Syrah's Vidalia plant, the Australian company said in a statement. The Louisiana facility is planned to process graphite from Mozambique to become the first US-based source of graphite anodes for the country's fast-growing electric vehicle and lithium-ion battery manufacturing industry.
