The novel anode material currently under development by DGI for use in sodium-ion batteries has passed a key milestone along the path to full-scale commercial production. In co-operation with a leading battery cell manufacturer, almost 4 kg of the anode material has been successfully coated onto 100 m of aluminium foil. Engineers at the manufacturer who supervised the coating process and subsequent mechanical testing of the foil commented that the DGI’s material coated easily and reliably, and that it exhibited outstanding adhesion.
“We had a very tight timescale for the coating trials,” said Peter Tierney, CEO of DGI, “and, while we had prepared an adequate supply of our anode material in its bulk form, we couldn’t find a UK company able to convert it into a powder with the correct particle size range for coating. The only way we could meet the deadline was to take a suitcase full of the stuff to the USA for milling, which raised a few eyebrows at US customs! However, the excellent trial results certainly made the effort and inconvenience worthwhile.”
