Li-S Energy Finalises Lithium-Sulfur Cells With 50x Power for Drones
Brisbane – November 10, 2026 -- Li-S Energy Limited (ASX: LIS) has finalised two high-power lithium-sulfur cell designs that deliver up to 50 times the power of traditional lithium-sulfur chemistry while keeping energy density close to 400 Wh/kg. The company has completed datasheets for both cells and shared them with partners under NDA.
Power cells target the multi-rotor drone segment
High power delivery has long limited lithium-sulfur chemistry to a narrow set of applications. Traditional cells typically discharge continuously at only 0.1C to 0.2C. Li-S Energy's 11Ah cell runs at 7C continuous, and the company is aiming the new range at multi-rotor drones, soldier-carried systems, robotics and communications.
The new cells deliver a continuous power density of 1,700 W/kg and a peak of 2,400 W/kg. Li-S Energy says this brings the technology into the fast multi-rotor UAV market.
