I am pleased to hand the company over to such an accomplished JM executive as Bob and am confident he and our 8,000 employees around the world will continue to build on JM’s 162-year track record of success.”

Pure Lithium Receives Australian Patent for "Lithium Metal Anode and Battery"6.8.2026 23:49:00 EEST | Press release

Pure Lithium Corporation, a vertically integrated next-generation lithium metal battery technology company, today announced that the Australian patent office has granted the company a patent (AU2025271196) titled “Lithium metal anode and battery.” Australia mines roughly half of the world’s lithium, yet has no domestic battery production at all; every battery the country uses is imported.
