Latest Lithium Sulfur Batteries 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 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 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.

Li-S Energy has received the first $1.9 million tranche of a $7.8 million ARENA grant and appointed Hatch to lead a feasibility study for scaling up its lithium-sulfur battery manufacturing to 1 GWh capacity.

Li-S Energy has made significant strides in Q4 2025, securing a major government grant, forging key defence partnerships, and commissioning Australia’s first lithium foil production line.

PPK Group reports record revenue at Craig International Ballistics and advances lithium sulfur battery technology, while preparing for a CEO transition and focusing on sovereign manufacturing.

Li-S Energy has accelerated its transition from research to manufacturing with a $7.8 million ARENA grant, new commercial partnerships, and plans for a large-scale production facility.
