TOKYO : Japan's Sumitomo Metal Mining said on Monday it will invest 16.9 million Canadian dollars ($12.5 million) in Canada's battery material company Nano One Materials to collaborate on manufacturing technology for the material. The move comes after Japan and Canada agreed to work more closely together to establishing sustainable and reliable global battery supply chains. Sumitomo Metal supplies the nickel-cobalt-aluminium (NCA) cathode materials for the Panasonic lithium-ion batteries used in Tesla electric vehicles (EVs).
