Latest Lithium Sulfur News

Li-S Energy has signed an agreement to evaluate its Australian-made lithium-sulfur batteries in Safesky Systems' tactical drone platforms. The collaboration opens a potential defence supply pathway, but commercial orders remain dependent on testing and customer procurement decisions.

Li-S Energy’s lithium-sulfur battery powered the Pegasus drone through an almost two-hour Queensland flight covering more than 75 kilometres. The result strengthens the technology’s aviation credentials, but the partners are still assessing commercialisation rather than announcing sales.

Li-S Energy has narrowed its FY26 loss and reached several commercialisation milestones, including a 2C Power Cell, international shipping approvals and its first lithium foil sale. But the ASX battery developer still needs customer offtake and fresh funding before its proposed 1 GWh manufacturing expansion can become reality.

Li-S Energy says its Geelong lithium-sulfur production line is complete and has delivered 10Ah Power Cells to the US Army for testing. The company is targeting its first commercial battery sale in 2027, while holding A$15.6 million in cash and investments and A$9.3 million in secured grants yet to be received.

Li-S Energy has inked a strategic collaboration with Australian defence firm EPE, unlocking pathways to international defence markets for its ultra-lightweight lithium sulfur batteries.

Li-S Energy has shipped its first lithium-sulfur battery cells to the US Army DEVCOM C5ISR Center, marking a key milestone in its commercialisation and opening a pathway into US defence procurement.

Li-S Energy reported a reduced net loss of $4.9 million in FY26, propelled by major technological advances and a $7.8 million ARENA grant to scale manufacturing. The company secured key regulatory approvals and expanded strategic defence partnerships, positioning itself at the forefront of sovereign lithium sulfur battery supply.

Li-S Energy marked key commercial and regulatory milestones in Q2 2026, including ISO 9001:2015 certification for its lithium foil line, first commercial foil sale, and US air transport approvals for lithium-sulfur cells. The company also completed a major Battery Testing Centre expansion and began deep-ocean cell testing with MSubs.

Li-S Energy has secured ISO 9001:2015 certification for its lithium foil production in Geelong and completed its first commercial shipment to a leading Australian battery research institution, marking a key step in establishing a sovereign lithium foil supply chain.

Li-S Energy has secured vital approvals to airfreight lithium-sulfur prototype cells to the United States, paving the way for direct engagement with US defence and drone sectors.

Li-S Energy secured $1.9 million from ARENA to fund a feasibility study scaling production to 1 GWh, expanded its Battery Testing Centre, and delivered its first drone battery pack under a government program, while progressing key transport certifications.

Li-S Energy narrows its loss to $1.21 million in H1 2026, propelled by a $7.8 million ARENA grant and key manufacturing milestones including Australia’s first lithium metal foil production line. Strategic defence and aerospace partnerships bolster its commercialisation drive.
