Li-S Energy, an Australian battery technology developer, claims that the successful creation of 100-micron thick pure lithium metal foils at its 2 MWh cell production line in Geelong has given them a new sovereign manufacturing capacity.
The business said that by producing high-quality lithium foils domestically, it can no longer rely on imported lithium foils to make the anode for its lithium-sulfur and lithium metal batteries.
The new production capabilities will improve the quality and consistency of Li-S Energy’s battery cells while cutting prices and lead times for materials, according to Steve Rowlands, chief technology officer.
“By producing foils in-house, we have tighter control over thickness, purity and handling conditions, all of which are critical for performance and safety,” he stated.
“This milestone accelerates our ability to develop custom anode architectures, supports higher throughput in our pouch cell line, and enables more rapid technology iterations.”
Li-S Energy Chief Executive Officer Dr Lee Finniear said the domestic foil production supports Australian battery supply chain resilience and marks a significant step forward for the country’s value-added lithium processing industry.
“This is a transformative moment for Australia’s battery industry,” he stated. “By reducing dependence on overseas supply chains, we substantially improve our cost base, enhance cell quality, and support the resilience of Australian manufacturing.”
“It also opens the door to export opportunities as international demand for high-purity lithium foil continues to grow.”
According to Finniear, the manufacturing milestone, which was made possible by an Australian government Industry Growth Program (IGP) funding of $1.76 million (USD 1.16 million), lays the groundwork for Li-S’s next manufacturing growth.
“Under the IGP, the company will also be installing equipment to roll, laminate and coat the lithium foils, allowing it to offer a broader suite of foil products for international markets and to scale up its proprietary nano-material coating technologies,” he stated.
Apart from utilizing the lithium metal foils to enhance its own lithium-sulfur and lithium metal batteries, Li-S Energy is also providing the foils to academic institutions, commercial businesses, and institutes engaged in battery research and development.
