Li-S Energy Limited announced on 9 October 2026 that it signed a collaboration agreement with Melbourne-based defence technology company Safesky Systems at Land Forces 2026 in Perth, targeting the supply of Australian-made lithium sulfur batteries for Safesky’s tactical drone fleet. The agreement establishes a framework for both companies to evaluate, test and integrate Li-S Energy’s cells and battery packs into Safesky platforms, with any move to commercial supply dependent on technical results and customer procurement decisions. The announcement highlights that Li-S Energy’s GEN3 cells are approaching 500Wh/kg, nearly double the energy density of conventional lithium-ion batteries, which could materially improve drone range, endurance and payload, including for Safesky’s VTRX fixed-wing VTOL platform and Sentinel multirotor UAV. Li-S Energy also emphasised the sovereign and allied supply chain benefits of its Geelong-made cells, which avoid graphite, nickel, cobalt and manganese, aligning with Safesky’s NDAA-compliant platforms and defence procurement requirements. Initial design evaluation is expected to begin in the current quarter, followed by battery pack integration and ground and flight testing.
Key Points
Li-S Energy signed a collaboration agreement with Safesky Systems at Land Forces 2026 in Perth.
The agreement targets supply of Australian-made lithium sulfur batteries for Safesky’s tactical drone fleet.
Li-S Energy and Safesky will jointly evaluate, test and integrate LIS cells and battery packs into Safesky platforms.
Commercial supply will depend on testing outcomes and Safesky customer procurement decisions.
Li-S Energy said its GEN3 cells are approaching 500Wh/kg, close to double conventional lithium-ion energy density.
Higher energy density could improve drone range, operating time and payload capacity.
The batteries are made in Geelong, Victoria and are promoted as supporting a sovereign allied supply chain.
Safesky’s current platforms mentioned are the VTRX fixed-wing VTOL tactical mothership and the Sentinel tactical multirotor UAV.
Initial design evaluation is expected to commence in the current quarter, with integration and flight testing to follow.
